An eternity ago a particular Linux kernel developer gave a series of "Why user space sucks" talks at Linux conferences. It was just going through strace logs and making fun of particularly bad examples.

Here's one instance: https://www.kernel.org/doc/ols/2006/ols2006v1-pages-441-450....

At some point I stared a lot at instruction level traces with Processor Trace or LBRs and usually I found some bad sequences in many programs, where things are implemented very inefficiently.

That talk is brilliant, and matches my experience unfortunately..

Do you know if there are videos of those talks posted anywhere?

while I wait for a video from 2006 to miraculously survive, some googling gave me these, though:
