Solarbird Jun 7

this was what our web server was looking like a couple of weeks ago when i went into emergency perf optimisation/reconfiguration mode and also ordered a new-to-us used CPU with two more cores and more than double the threads that still fit in our motherboard's socket after a post on my federated blog went low-key viral (55,000ish "impressions")

i like the load average of 60.10 but i particularly like the mariadb task using 1182% of CPU

i don't actually know what that means and i think top was confused

@moira I read 1182% CPU as "11.82 core-seconds / second". But, not knowing how many cores (or threads, I guess) that machine has, I have no idea if that is plausible.

@vatine @moira You are exactly right! You can exceed 100% with a multi-threaded program that's one process, using multiple cores simultaneously.
Note that this is impossible to do in Python due to the GIL, despite the terminology; only one thread is allowed to execute at a time.

@trouble @vatine but that old CPU only had six cores (and threads) so

confusion

@moira @trouble Then I have no plausible explanation, other than "top, or the kernel, seems confused".

@vatine @trouble top

and/or the kernel

and me. definitely me
