When it comes to network performance, there are two main limiting factors that will slow you down: bandwidth and latency. If you’re streaming video, the difference between a 2Mb 1 connection and a 20Mb connection will surely be appreciated. Latency is defined as…. and reduction in latency. and reduction in latency.
As organizations digitally transform, they’re also accelerating the speed of software delivery. Note : you might hear the term latency used instead of response time. Both latency and response time are critical to ensure reliability. Latency primarily focuses on the time spent in transit. The Apdex score of 0.85
After content ingestion, inspection and encoding, the packaging step encapsulates encoded video and audio in codec agnostic container formats and provides features such as audio video synchronization, random access and DRM protection. Uploading and downloading data always come with a penalty, namely latency.
By monitoring metrics such as error rates, response times, and network latency, developers can identify trends and potential issues, so they don’t become critical. Load time and network latency metrics. Minimizing the number of network requests that your app makes can improve performance by reducing latency and improving load times.
Telltale provides Edgar with latency benchmarks that indicate if the individual trace’s latency is abnormal for this given service. Telltale’s anomaly analysis looks at historic behavior and can evaluate whether the latency experienced by this trace is anomalous. Is this an anomaly or are we dealing with a pattern?
Measuring application performance is increasingly important because as organizations digitally transform, they’re also accelerating the speed of software delivery. Note : you might hear the term latency used instead of response time. Both latency and response time are critical to ensure reliability. The Apdex score of 0.85
This means that youre able to handle sudden traffic surges without the hassle of resource monitoring and without compromising on speed. This means that you can reduce latency and speed up your content delivery times , regardless of where your customers are based.
For example, data collected on load actions can include navigation start, request start, and speed index metrics.

We are standing on the eve of the 5G era… 5G, as a monumental shift in cellular communication technology, holds tremendous potential for spurring innovations across many vertical industries, with its promised multi-Gbps speed, sub-10 ms low latency, and massive connectivity. Throughput and latency. What about UHD video?
This may be the opposite of my famous [shouting video]: This time I'm suppressing vibration to make a disk work.) From these outputs I try to determine if the problem is: - **The workload**: High-latency disk I/O is commonly caused by the workload applied. Note the sdb latencies range from 32 ms to over 2 seconds!
In this fast-paced ecosystem, two vital elements determine the efficiency of this traffic: latency and throughput. LATENCY: THE WAITING GAME Latency is like the time you spend waiting in line at your local coffee shop. All these moments combined represent latency – the time it takes for your order to reach your hands.
The video is on [youtube]: The slides are on [slideshare] or as a [PDF]: I work on many areas of performance, but recently I've had a lot of demand to talk about BPF. Ford, et al., “TCP on Upcoming Sapphire Rapids CPUs,” [link] Oct 2020 - [Liu 20] Linda Liu, “Samsung QVO vs EVO vs PRO: What’s the Difference?
Check out this ~15-minute video on how we implemented this process-first approach at Rechat. Were experiencing high latency in responses. The AI is taking too long to reply; we need to speed it up. This trade-off affects speed and quality. So, you trade some performance for speed and cost savings.
Compared to the most recent master version of libaom (AV1 reference software), SVT-AV1 is similar in compression efficiency and at the same time achieves significantly lower encoding latency on multi-core platforms when using its inherent parallelization capabilities. The testing has been performed on Windows, Linux, and macOS platforms.
The video is now on [YouTube]: The slides are [online] and as a [PDF]: first prev next last / permalink/zoom In Q&A I was asked about CXL (compute express link) which was fortunate as I had planned to cover it and then forgot, so the question let me talk about it (although Q&A is missing from the video).

Why speed matters, examples of the impact saving a few seconds of load time has had on revenue and engagement. Bandwidth, latency and it's fundamental impact on the speed of the web. Impact of performance improvements Optimizing the Critical Rendering Path for Instant Mobile Websites (Video) What are responsive websites made of?
This typically happens once per server and takes up valuable time — especially if the server is very distant from the browser and network latency is high. Video or audio WebVTT tracks. Speed Up Next-Page Navigations With Prefetching ,” Addy Osmani. (il). This is where globally distributed CDNs really help!) Value of as.
Performant – DynamoDB consistently delivers single-digit millisecond latencies even as your traffic volume increases. DynamoDB automatically re-distributes your data to healthy servers to ensure there are always multiple replicas of your data without you needing to intervene.
If you've invested countless hours in speeding up your pages, but you're not using performance budgets to prevent regressions, you could be at risk of wasting all your efforts. It's only tracked on certain elements, e.g., IMG and VIDEO. INP logs the latency of all interactions throughout the entire page lifecycle.
Elon Musk’s need for speed. However, there is excitement around Starlink for other reasons – namely, the implications it might have for internet speed and latency – even by just a small amount (20 milliseconds on average). This ultimately guides us to one conclusion: Speed is incredibly important.
Moreover, a GSI''s performance is designed to meet DynamoDB''s single digit millisecond latency - you can add items to a Users table for a gaming app with tens of millions of users with UserId as the primary key, but retrieve them based on their home city, with no reduction in query performance. What was the highest ratio of wins vs. losses?
When it comes to marketing your website, there are a lot of different aspects to consider, such as speed, SEO, conversation rates, bounce rate, and many others. Image CDN Using a content delivery network like KeyCDN, or what we also call an image CDN , can be one of the easiest and fastest ways to speed up the delivery of your images.

Network latency. Network Latency. With the evolution of cloud technologies, such as Single Page Applications (SPAs), Web APIs, and Model View Controller (MVC), network latency has become a crucial factor to be monitored. Network latency can be affected due to. Connection time. Database connectivity. Hardware resources.
High-speed networks through 5G may represent the next generation of cord cutting. I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. Reliability will be an even bigger problem than latency.
Latency Optimizers” – need support for very large federated deployments. 5G expects a latency of 1ms , which considering that the speed of light means the data center can’t be more than 186 miles away, or 93 miles for a round trip, assuming an instant response. Watch the Video.
I summarized these topics and more as a plenary conference talk, including my own predictions (as a senior performance engineer) for the future of computing performance, with a focus on back-end servers. Ford, et al., “TCP on Upcoming Sapphire Rapids CPUs,” [link] Oct 2020 - [Liu 20] Linda Liu, “Samsung QVO vs EVO vs PRO: What’s the Difference?
Largest Contentful Paint (LCP) LCP measures the perceived load speed of a webpage from a user’s perspective. This could be an image, a block of text, or even an embedded video. The shorter the TTFB, the better the perceived speed of the site from the user’s perspective. Time to First Byte over time. LCP in seconds.

We become annoyed when we run a speed test on our broadband provider only to find that, on a good day, we are getting maybe half of the rated download speed we are paying for, and the upload speed is likely much worse. But to prevent running afoul of latency (the 2 nd fallacy), we must also be careful not to download too little!
While Wi-Fi theoretically can achieve 5G-like speeds, it falls short in providing the consistent performance and reliability that 5G offers, including low latency, higher speeds, and increased bandwidth. Additionally, frequent handoffs between access points can lead to delays and connection drops.
Performance issues surrounding Availability Groups typically were related to disk I/O or network speeds. Our customers who deployed Availability Groups were now using servers for primary and secondary replicas with 12+ core sockets and flash storage SSD arrays providing microsecond to low millisecond latencies. one without a replica).
This may be the opposite of my famous [shouting video]: This time I'm suppressing vibration to make a disk work.) From these outputs I try to determine if the problem is: - **The workload**: High-latency disk I/O is commonly caused by the workload applied. I managed to read over 99.9999% of disk sectors successfully. Hit Ctrl-C to end.

Fast-forward 30 years, and website technology has changed significantly — we have images, stylesheets, JavaScript, streaming video, AJAX, animation, WebSockets, WebGL, rounded corners in CSS — the list goes on. While it looks unassuming, it laid the foundation for the web we have today. Large scale blogs.
rich multimedia (animations, video, audio). Huge reach, plus the licensing of On2's video codecs , made Flash the default video delivery mechanism for many years. a lab's worth of sensors , including: cameras (both still and video). Unfortunately, much has already been done to speed the web's irrelevance.
I can count on one hand the number of teams I’ve worked with who have goals that allow them to block launches for latency regressions, including Google products. The landing pages of popular tools talk about “speed” without context. And still framework marketing continues unmodified.
For instance, you might set up rules to send video streaming requests to data center A and image loading requests to data center B. â€Performance Matters: The physical distance between a user and a data center impacts the data transfer speed. What is “Originâ€?An
. ## Observability Here's the big picture of performance observability tools on Linux, from my [Linux performance] page, where I also have diagrams for other tool types, as well as videos and slides of prior Linux performance talks: I also have a USE Method: Linux Performance Checklist , as a different way to navigate and apply the tools.
These rules determine to which origin data center each request will be directed, based on customer-defined conditions, within the Content Delivery Network (CDN) infrastructure.For instance, you might set up rules to send video streaming requests to data center A and image loading requests to data center B. What is “Origin”?An
The Lighthouse Performance score is based on some of the most important performance metrics : First Contentful Paint, First Meaningful Paint, Speed Index, Time to Interactive, First CPU Idle, and Estimated Input Latency. When it comes to network speed, Lighthouse gives you three options – and no others.
It’s used extensively in our media processing platform, which includes services like Archer and runs features like video encoding and title image generation on tens of thousands of Amazon EC2 instances. We are constantly innovating on video encoding technology at Netflix, and we have a lot of content to encode. We have one file?
A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”. Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.
