TCP: Establishing a reliable connection to the server.
Its partitioned log architecture supports both queuing and publish-subscribe models, allowing it to handle large-scale event processing with minimal latency. Kafka clusters can be deployed in Kubernetes using Helm charts to simplify scaling and management across multiple servers.
Concatenating our files on the server: Are we going to send many smaller files, or are we going to send one monolithic file? Plotted on the same horizontal axis of 1.6s, the waterfalls speak for themselves: 201ms of cumulative latency; 109ms of cumulative download. 4,362ms of cumulative latency; 240ms of cumulative download.
When it comes to network performance, there are two main limiting factors that will slow you down: bandwidth and latency. Latency is defined as…. Where bandwidth deals with capacity, latency is more about speed of transfer 2. and reduction in latency. and reduction in latency. Bandwidth is defined as….
These events are promptly relayed from the client side to our servers, entering a centralized event processing queue. Collecting Raw Impression Events As Netflix members explore our platform, their interactions with the user interface spark a vast array of raw events.
Redis stands for REmote DIctionary Server, created in 2009 by Salvatore Sanfilippo. Both Redis and Memcached are: NoSQL in-memory data structures Written in C Open source Used to speed up applications Support sub-millisecond latency In 2014, Salvatore wrote an excellent StackOverflow post on […].
Caching is the process of storing frequently accessed data or resources in a temporary storage location, such as memory or disk, to improve retrieval speed and reduce the need for repetitive processing.
A lot of people surmise that TTFB is merely time spent on the server, but that is only a small fraction of the true extent of things. The first—and often most surprising for people to learn—thing that I want to draw your attention to is that TTFB counts one whole round trip of latency. But what else is TTFB?
This is because file-size is only one aspect of web performance, and whatever the file-size is, the resource is still sat on top of a lot of other factors and constants—latency, packet loss, etc. Taking a very reductive and simplistic view of how files are transmitted from server to client, we need to look at TCP. packet loss).
Too many concurrent server requests can lead to website crashes if youre not equipped to deal with them. You can free up space and reduce the load on your server by compressing and optimizing images. This means that youre able to handle sudden traffic surges without the hassle of resource monitoring and without compromising on speed.
Microservices-based architectures and software containers enable organizations to deploy and modify applications with unprecedented speed. At the lowest level, SLIs provide a view of service availability, latency, performance, and capacity across systems. However, cloud complexity has made software delivery challenging.

It’s right there in the name!
By Karthik Yagna , Baskar Odayarkoil , and Alex Ellis Pushy is Netflix’s WebSocket server that maintains persistent WebSocket connections with devices running the Netflix application. In our case, we value low latency — the faster we can read from KeyValue, the faster these messages can get delivered.
In that scenario, the system would need to deal with the data propagation latency directly, for example, by use of timeouts or client-originated update tracking mechanisms. We started seeing increased response latencies and leader servers running at dangerously high utilization.
Endpoints include on-premises servers, Kubernetes infrastructure, cloud-hosted infrastructure and services, and open-source technologies. Observability can identify the baseline user experience and allow teams to improve it by optimizing page load times or reducing latency. Why full-stack observability matters.
The roles and responsibilities of ITOps team members include the following: A system administrator configures servers, installs applications, monitors the health of the system, and fixes and upgrades hardware. This includes response time, accuracy, speed, throughput, uptime, CPU utilization, and latency. Performance.
RISELabs , those wonderfully innovative folks over at Berkeley, have uplifted their Anna datatabase —a shared-nothing, thread-per-core architecture to achieve lightning-fast speeds by avoiding all coordination mechanisms—to become cloud-aware. What's changed ?
A span: Represents a unit of work, such as a network call from one service to another (a client/server relationship) or a purely internal action (e.g., Telltale provides Edgar with latency benchmarks that indicate if the individual trace’s latency is abnormal for this given service. starting and finishing a method).
A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. This server is spending about a third of its CPU cycles just checking the time! Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? 30.14% in the middle of the flame graph. in total.
Data collected on page load events, for example, can include navigation start (when performance begins to be measured), request start (right before the user makes a request from the server), and speed index metrics (measure page load speed). connectivity, access, user count, latency) of geographic regions.
Think about items such as general system metrics (for example, CPU utilization, free memory, number of services), the connectivity status, details of our web server, or even more granular in-application tasks like database queries. Let’s click “Apache Web Server apache” now.
By removing disk-based storage and the challenge of copying data in and out of memory, query speeds in SQL Server can be improved by orders of magnitude. TempDB is one of the biggest sources of latency in […].
You will need to know which monitoring metrics for Redis to watch and a tool to monitor these critical server metrics to ensure its health. Understanding Redis Performance Indicators Redis is designed to handle high traffic and low latency with its in-memory data store and efficient data structures.
Identifying key Redis metrics such as latency, CPU usage, and memory metrics is crucial for effective Redis monitoring. To monitor Redis instances effectively, collect Redis metrics focusing on cache hit ratio, memory allocated, and latency threshold.
This query is performed by a Domain Name Server (DNS server) or servers nearby that have been assigned responsibility for that hostname. You can think of a DNS server as a phone book for the internet. A DNS server maintains a directory of domain names and translates them to IPs.

Percona Server for MongoDB (PSMDB) supports all types of compression and enterprise-grade features for free. This can further reduce the amount of data that needs to be transmitted between server and client over the network. In this blog, we will discuss both data and network-level compression offered in MongoDB. I am using PSMDB 6.0.4
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
Edge servers are the middle ground – more compute power than a mobile device, but with latency of just a few ms. The kind of edge server envisaged here might, for example, be integrated with your WiFi access point. As such, web workers are a natural target to offload to a more powerful server.
With Tel Aviv being the technology capital of Israel, it's the ideal edge server location. The image below shows a significant drop in latency once we've launched the new point of presence in Israel. In fact, latency has been reduced by almost 50%! Compared to other countries in the region, the connection speed has room to grow.
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.
Balancing Low Latency, High Availability and Cloud Choice Cloud hosting is no longer just an option — it’s now, in many cases, the default choice. Even then, AWS can elect to ‘move’ your server to different physical hardware without warning, a process that involves ‘only’ a few seconds of downtime. Why are they refusing?
I propose four key ingredients: Definition: What is "performance" beyond page speed? Tim Berners-Lee tweets that 'This is for everyone' at the 2012 Olympic Games opening ceremony using the NeXT computer he used to build the first browser and web server. Improving latency for one scenario can degrade it in another.
The POP is strategially located within the country and lowers latency overall. KeyCDN is always on the lookout for ways to minimize latency and accelerate asset delivery worldwide. For more POPs planned, check our current network for a list of both active and planned edge server locations. Hola Mexico!
Introduction Caching serves a dual purpose in web development – speeding up client requests and reducing server load. Redis Revealed: An Overview Redis, a renowned open-source, in-memory remote dictionary server, stands out for its diverse data structures and advanced features. Data transfer technology.
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.
With just one click you can enable content to be distributed to the customer with low latency and high-reliability. The first set of features that CloudFront is launching today include: Multiple Origin Servers: the ability to specify multiple origin servers, including a default origin, for a CloudFront download distribution.
Sometimes tracking down a bug is as simple as paying attention to server dashboards, spending a few minutes in a profiler, or looking at compiler warnings. Server CPU Surprise. A few years ago I spent a few weeks doing some memory investigations on live game servers. The first server process that I profiled was… odd.
Hardware Memory The amount of RAM to be provisioned for database servers can vary greatly depending on the size of the database and the specific requirements of the company. Some servers may need a few GBs of RAM, while others may need hundreds of GBs or even terabytes of RAM. Benchmark before you decide.
As a MySQL database administrator, keeping a close eye on the performance of your MySQL server is crucial to ensure optimal database operations. However, simply deploying a monitoring tool is not enough; you need to know which Key Performance Indicators (KPIs) to monitor to gain insights into your MySQL server’s health and performance.
Many were hesitant to sacrifice site speed for the added layer of security if they felt like they didn’t need it. In a vacuum, an SSL certificate does add some additional latency, as it requires 2 extra round trips to establish a secure connection before sending any data to the browser. So what’s the truth? Is SSL slow?
