Hey. Some of you may know Honza's images about CPU utilization and memory usage when using LTO [1]. Last week I played with Chromium and Firefox and I wanted to visualize their utilization. That's why I came up with a new script [2].
You can easily wrap a command and the script generates graphs for you:. The script uses modern psutil library and plots through a great matplotlib: $ usage-wrapper.py -v -t postgresql 'make -j16' ... $ eog usage.svg There's a gallery of the collected reports for Firefox and Chromium: https://gist.github.com/marxin/223890df4d8d8e490b6b2918b77dacad and yes, we have a LTO regression since GCC 9 that I'm going to take closer to.
