Pinning the frequency is great for reproducibility yeah

For squeezing perf in prod better to overclock (with good cooling)

My Spanish ISP does not allow to use IPv6 unfortunately..

That sucks. I'm also in the EU and all CGNAT-using ISPs offer dualstack here

man... that sucks :(

There are still ISP's that REALLLLLLY don't wanna think about ipv6 LOL

and i'm not totally sure why?

sorry you have to put up with that :(

Thanks for sharing! Happy to get feedback :)

There is nothing more satisfying than owning, end to end, the software and the hardware you use without relying on abusive cloud corporations. Internet is us, not them. Break free from censorship. Learn how to self-host at home, and be truly /libre/.

Nice!

Fair enough yeah. IMO microbenchmarks are useful for trying to gain intuition and propose the next incremental improvement. In real world measuring is mandatory, if you don't want to risk pessimizing the code

The wild thing about locks in particular is that microbenchmarks will cause you to make „optimizations” that are the opposite of what benefits real world workloads.

Very good point, should add this

Yeah that's quite right, you shouldn't be using spinlock without pinned threads

Thanks for sharing! Happy to get feedback :)

Note that I don't recommend spinlock for most cases, only when there is a 1:1 mapping between threads and phsycal CPU cores, and only after measuring
