What about short-lived processes, like a service restarting in a loop? Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side.

With the rapidly increasing use of smartphones and ease of access to the internet across the globe, testing has spread across vast platforms. For example, if you are using internet banking via a Mobile Web application, it will not allow you to save cards or mark any transaction as favourite. What are Mobile Web Applications?

LoadView – Best Practices and Process. It helps assess how a site, web application, or API will respond to various traffic, without adding any additional infrastructure. Executing an internal test can tell you how well your application or site handles an increase in traffic, but it will never reflect real-world conditions.

Cloud computing solutions work as a catalyst in this process due to the easily available high processing power of the cloud, resulting in faster deployments. Centralizes the Processes.

Meanwhile, on Android, the #2 and #3 sources of web traffic do not respect browser choice. Modern browsers like Chrome and Samsung Internet support a long list of features that make web apps more powerful and keep users safer. Hardware access APIs, notably: Geolocation. PWA Feature Detector. Web OTP (for easier/faster sign-in).

Looking at current hardware and software security research, however, we are seeing a number of technologies that are being developed that limit this type of broad interoperability. Today, data encryption is commonly used for communication, but processors typically store and process data in cleartext in local memory.

Let’s face it – the ideal load test emulates real world traffic, yet most load testing software doesn’t come close. Today we’ll be reviewing LoadView , an on-demand load-testing platform from Dotcom-Monitor that makes realistic load testing possible without an up-front investment in hardware or software infrastructure.

There are several theories about why this performance drops – could be related to video processing, or perhaps the RDP session – but what’s obvious is that CPU is much higher than it used to be. I didn’t want to be testing using an older browser than most of my traffic. Consider the Linux Agents.

Error tracking is the process of proactively identifying issues and fixing them as quickly as possible. Monitoring errors on the front-end requires a bit more work because front-end performance is highly dependant on the user’s hardware, software and connection. Worse still, they could start spreading the word on Twitter.

This second metric measures the time between when the user interacts with a page, clicking on a link or a button for example, and when the browser processes that click. This is applicable to pages that receive little to no traffic, so small sites without field data don’t need to be worried. First Input Delay (FID). CrUX is Chrome only.

There's also a ZFS send/recv code path that should try to use the TASK_INTERRUPTIBLE flag (as suggested by a coworker), to avoid a kernel hang (can't kill -9 the process).

So, if we created an overview of all the things we have to keep in mind when improving performance — from the very start of the process until the final release of the website — what would that list look like? Also, as Patrick Meenan suggested, it’s worth to plan out a loading sequence and trade-offs during the design process.

Micro-optimizations are great for keeping performance on track, but it’s critical to have clearly defined targets in mind — measurable goals that would influence any decisions made throughout the process.

This is because HTTP/3 and QUIC mainly help deal with the somewhat uncommon yet potentially high-impact problems that can arise on today’s Internet. On the Internet, however, we typically have a long series of connected pipes , some of which can be wider than others (leading to so-called bottlenecks at the narrowest links).
