Perf Trace, Private Tux - Solving Linux mysteries
Perf trace is a versatile, flexible powerful option in the perf toolbox, allowing to combine the power of strace with additional capabilities, which give you a multi-dimensional view of your system's behavior. For instance, by default, strace is a bit more difficult to follow and analyze, whereas perf trace helps more easily bucket results per thread, filter out unnecessary information, and conversely, zero in on the specific data you need.
Hopefully, this tutorial is a good reference point for getting started with perf trace. You do need some background knowledge, you need to know how your software behaves, but then you can use it to figure out possible performance bottlenecks, and improve and optimize its execution. Perf may also need some tweaking to run well in userspace, and you have tons of flags and options to narrow down the troubleshooting to what you need. And that would be all for today.

How to Test Your Website Speed on Linux - Linux Stans
Website speed, often called website performance, refers to the amount of time a web browser renders web pages from a specific site.
A site’s loading speed can significantly affect user experience (UX). For example, a slow website response time (SRT) can lead to high bounce rates. Subsequently, having a poorly performing website can harm your search engine optimization (SEO) efforts.
This article will cover three tips for testing a website’s speed, including how to do it in a Linux Terminal. By identifying the areas for improvement, website owners can optimize website speed more efficiently.

| elementary Blog: Updates for July, 2022
Firstly, thank you so much for your patience this month! I’ve been out sick with COVID for about 3 weeks, so I haven’t been able to contribute much or organize releases this month. I want to give a special thanks to our volunteer community who has continued to make improvements and move forward on projects in my absence. I’m excited to catch up and get back to work to make the most of the rest of this month. Having said that, this is going to be a very brief updates post. [...] A ton of energy in the community has gone into Gtk 4 porting for OS 7 and beyond. The team is making steady progress on porting System Settings and we landed the Gtk 4 port for Sideload. We’ve also uncovered some style issues and gaps in style constants, so if you’re working on porting your app to our Flatpak Platform 7, know that we’ll be releasing some fixes soon. I want to give some special acknowledgment to Owen Malicsi who has taken a lot of ownership over Gtk4 porting. Owen started contributing to elementary to improve his development skillset in preparation for college, and he’s done an amazing job both in successfully porting components to Gtk 4 as well as identifying blockers and creating discussions around refactoring for Gtk 4 paradigms. I’m super proud of his growth and contribution and we wish him well in his studies! Thanks Owen! Read on |
