When recurring 10–15 second outages made the database behind #LinkedIn’s user feed briefly unavailable - with no useful logs - engineers turned to off-CPU profiling with #eBPF to find the root cause.

The failures were ephemeral, patternless, and had no clear external trigger.

Here is how they solved it ⇨ https://bit.ly/3PS1RtN

If you have been using #py5 for a while, this page about #matplotlib integration is a documentation gem It opens up the possibility of making "live", real time and interactive, maplotlib charts, but even if you are not into #dataviz, it shows the beautiful #profiling tools integrated with py5 and how to use #threading to improve performance. In the end you also learn about named colors and the clever "Colormap Color Mode" feature.

Allegro experimented with different performance optimization options to improve #ApacheKafka producer tail latency and eventually switched all its clusters to the XFS filesystem.

How many people are running high-frequency sampling #profilers on their desktops though?

IOW, why pessimize for the vast majority of users?

Modern sampling-based #profilers for #Java make it possible to investigate performance problems with #opensource tools. You can choose between:
• a slightly imprecise but easy-to-use tool with a simple UI (VisualVM)
• a built-in tool with information on GC and more (JFR)
• a tool that has lots of options and can show information on C/C++ code (async-profiler)

Try them out to know what to use when encountering your next performance problem: http://bit.ly/3GL10n0
