I began writing this article in early July 2023 but began to feel a little underwhelmed by it and so left it unfinished. Compressing them over the network: Which compression algorithm, if any, will we use? Caching them at the other end: How long should we cache files on a user’s device? in this article.
In this post I want to look at how CSS can prove to be a substantial bottleneck on the network (both in itself and for other resources) and how we can mitigate it, thus shortening the Critical Path and reducing our time to Start Render. This article is getting way, way more forensic than I intended. Employ Critical CSS.
For the longest time now, I have been obsessed with caching. I think every developer of any discipline would agree that caching is important, but I do tend to find that, particularly with web developers, gaps in knowledge leave a lot of opportunities for optimisation on the table. Want to know everything (and more) about HTTP cache?
There are two effective methods to improve the load time — data caching and using a content delivery network (CDN). Our article aims to compare them in terms of speed of data load. When we talk about the speed of a website, most often we mean the speed of its content loading.
How To Design For High-Traffic Events And Prevent Your Website From Crashing How To Design For High-Traffic Events And Prevent Your Website From Crashing Saad Khan 2025-01-07T14:00:00+00:00 2025-01-07T22:04:48+00:00 This article is sponsored by Cloudways Product launches and sales typically attract large volumes of traffic.
A classic example is jQuery, that we might link to like so: There are a number of perceived benefits to doing this, but my aim later in this article is to either debunk these claims, or show how other costs vastly outweigh them. Users might already have the file cached. Penalty: Network Negotiation. It’s convenient.
Time To First Byte: Beyond Server Response Time Time To First Byte: Beyond Server Response Time Matt Zeunert 2025-02-12T17:00:00+00:00 2025-02-13T01:34:15+00:00 This article is sponsored by DebugBear Loading your website HTML quickly has a big impact on visitor experience. But actually, theres a lot more to optimizing this metric.
This gives fascinating insights into the network topography of our visitors, and how much we might be impacted by high latency regions. These intermediates fall outside of the scope of this article, but if you’ve ever run a traceroute , you’re on the right lines. That’s exactly what this article is about. What is RTT?
That data doesn't change usually, but the application, in each request, must connect, execute the correct instructions to read the data, pick it up from the network, etc. A solution to that problem could be using a cache, but how do you implement it? In that article, I explain how to use a basic cache in Spring Boot.
Performance Game Changer: Browser Back/Forward Cache. Performance Game Changer: Browser Back/Forward Cache. With that caveat out of the way, let’s get to the guts of the article: What is the Back/Forward Cache and why does it matter so much? Didn’t The HTTP Cache Do All That Anyway? Barry Pollard.
I can reload the exact same page under the exact same network conditions over and over, and I can guarantee I will not get the exact same, say, DOMContentLoaded each time. What if another file on the critical path had dropped out of cache and needed fetching from the network? In fact, I do that on this site. Signal vs. Noise.
In this example configuration, the ngsegment namespace is backed by both a Cassandra cluster and an EVCache caching layer, allowing for highly durable persistent storage and lower-latency point reads. "persistence_configuration":[ Developers just provide their data problem rather than a database solution!
This allows the app to query a list of “paths” in each HTTP request, and get specially formatted JSON (jsonGraph) that we use to cache the data and hydrate the UI. ecosystem was chosen for this new service deserves an article in and of itself. video titles, descriptions) could be aggressively cached and reused across multiple requests.
Bloom, these data structures have found applications in various fields such as databases, caching, networking, and more. In this article, we will delve into the concept of Bloom filters, their functioning, explore a contemporary real-world application, and illustrate their workings with a practical example.
Introducing gnmi-gateway: a modular, distributed, and highly available service for modern network telemetry via OpenConfig and gNMI By: Colin McIntosh, Michael Costello Netflix runs its own content delivery network, Open Connect , which delivers all streaming traffic to our members.
Metrics provide a unified and standardized definition to numerical data points over a period of time (for example, network throughput, CPU usage, number of active users, and error rates), whereas logs address traditional logging and allow you to handle logging information in an aggregated fashion.
However, let’s take a step further and learn how to deploy modern qualities to PWAs, such as offline functionality, network-based optimizing, cross-device user experience, SEO capabilities, and non-intrusive notifications and requests. When developing a PWA, you can cache the application shell’s resources and assets in the browser.
Since that presentation, Pushy has grown in both size and scope, and this article will be discussing the investments we’ve made to evolve Pushy for the next generation of features. As a networking team, we naturally lean towards abstracting the communication layer with encapsulation wherever possible.
Oddly enough we encountered this error to a third party website while writing this article. ISPs do cache DNS however which means if your first provider goes down it will still try to query the first DNS server for a period of time before querying for the second one. So DNS services definitely go down!
Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. The cache is invalidated on a time basis. Creating an On-Demand builder.
Key Takeaways Redis offers complex data structures and additional features for versatile data handling, while Memcached excels in simplicity with a fast, multi-threaded architecture for basic caching needs. Redis is better suited for complex data models, and Memcached is better suited for high-throughput, string-based caching scenarios.
This header can be set on the response of any network resource, such as XHR, fetch, images, HTML, stylesheets, etc. For this article, that’s all we’ll need to start exposing the value and leave other more specific articles to go deeper. Setting Server-Timing. More after jump! For Images, Stylesheets, JS files, the HTML Doc, etc.
In that spirit, what we’re looking at in this article is focused more on the incremental wins and less on providing an exhaustive list or checklist of performance strategies. I’m going to audit the performance of my slow site before and after the things we tackle in this article. Again, every millisecond counts. Lighthouse.
I keep seeing many articles and talks on “tuning” discussing how creating new indexes speeds up SQL but rarely ones discussing removing them. The more indexes, the more the requirement of memory for effective caching. Cache requirements for indexes are generally much higher than associated tables.
In this article, I’ll highlight some of the work we did and how we were able to achieve our speed. For this article, we will focus on the first three and the performance adjustments for these. And while you can usually cache the full page of an article, the same is not true of many shop pages and elements.
In this article, we’re going to learn how to handle real-time updates on the client-side using GraphQL. We’ll be learning how to do this with GraphQL Features like Cache Update, Subscriptions, and Optimistic UI. Updating the cache directly using update function on the useMutation. Then we go to our index.js to import and use it.
According to Mozilla Developer Network, the Map object holds key-value pairs and remembers the original insertion order of the keys. WeakMap can be used in two areas of web development: caching and additional data storage. The result from a function can be cached so that whenever the function is called, the cached result can be reused.
This article is part of a series in which I attempt to use the web under various constraints, representing a given demographic of user. Failing that, we are usually able to connect to home or public WiFi networks that are on fast broadband connections and have effectively unlimited data. As for mobile network connection type, 84.7%
If you’ve ever tried to build a web application that is completely offline first, you’ll know how tricky it can be to make changes to the users cache when you do make updates to the site and the user has connectivity. You’ll also learn how to refresh the page, so that the user is up to date and has the latest version of any cached files.
In my last article , I suggested using the SaveData API to deliver a different, more performant, experience to users that expressed that desire. In this article, I want to spend a bit more time on this, and also look at other signals we can similarly use to help us make decisions on what to load on our websites. Barry Pollard.
This article is sponsored by Storyblok. As you may already know, image optimization is the process that a high-quality image has to go through to be delivered in ideal conditions, sometimes with the help of an Image Transformation API and a global Content Delivery Network (CDN) to make the process simpler and scalable. Alba Silvente.
Next, we’ll look at how to set up servers and clients (that’s the hard part unless you’re using a content delivery network (CDN)). Practical HTTP/3 deployment options ( current article ). You would, however, be hard-pressed even today to find a good article that details the nuanced best practices. HTTP/3 performance features.
In this article, I will highlight a few core features that every headless CMS should provide. The delivery of static assets in formats such as WebP via a Content Delivery Network (CDN) is also crucial to serving your users a fast website. From a developer perspective, not only static assets need to be cached on a CDN.
How To Fix Largest Contentful Issues With Subpart Analysis How To Fix Largest Contentful Issues With Subpart Analysis Matt Zeunert 2025-03-06T10:00:00+00:00 2025-03-06T14:50:25+00:00 This article is sponsored by DebugBear The Largest Contentful Paint (LCP) in Core Web Vitals measures how quickly a website loads from a visitors perspective.
These statements and articles typically skip over some crucial technical details , are lacking in nuance, and usually are only partially correct. In this article series, I will discuss the new protocol, especially its performance features , with more nuance. We will discuss these features in more depth later in this article.
It also lists cached resources and identifies unused Javascript. It graphs server, network, CSS, Javascript, critical content, and image optimizations to show the potential savings you could gain by incorporating fixes into your site. Network and CPU are throttled for lab data tests for more realistic conditions.
In this article, I describe major architectural decisions we made and techniques we used. I can recommend this article by Peter Morville and Jeffrey Callender for further reading. So, the only way was to cache all necessary data to minimize interaction with RDBMS. There is a lot of information about faceted search on the web.
Answering Common Questions About Interpreting Page Speed Reports Answering Common Questions About Interpreting Page Speed Reports Geoff Graham 2023-10-31T16:00:00+00:00 2023-10-31T17:06:18+00:00 This article is sponsored by DebugBear Running a performance check on your site isn’t too terribly difficult. That’s what this article is about.
As I was determined to become great at my new occupation regardless of my location, I read every sysadmin book, article, and magazine I could find on the shelf. I didn't end up getting published in SysAdmin directly, but my performance work did make it as a feature article (thanks Matty). Or even on a plane.
In this article, we will review what third-party resource requests are, consider how impactful they can be to the user experience, and discuss common optimization strategies to reduce the impact on the user experience. And JavaScript can certainly make requests for additional network resources.
This article is intended to be used as a primer for managing complex states in a Next.js Unfortunately, the framework is way too versatile for us to cover all possible use cases in this article. It would be beyond the scope of this article to suggest when to use one or another, so let’s keep it simple by saying: useState.
You need to beware that slow server response times can significantly increase TTFB, often due to server overload, network issues, or un-optimized logic on the server side. You need to beware of large HTML files or slow network connections because they can lead to longer download times.
Today, we’ll address storing and serving files for both single-server and scalable deployments while considering factors like compression, caching, and availability. If you’re on the latter end of this scale, you probably need more specialized advice than this article is prepared to give. Option 1: Default Django. Media Files.
In this second article, I’ll go over some key technical highlights from the project. In the first article, I briefly discussed the technical stack that includes a React-based front-end framework, Next.js Definitely read up on the strategy and reasoning behind this stack in the first article if you missed it.
