on 2P epyc is 96cores x 2 threads per core x 2 socket => 384 logical cpu

so 100k threads mean 260 threads per cpu, which is not so much then...

And with EPYC Genoa-X there's over 1GB of L3 cache per socket, so the 800MB of kernel stacks mentioned (probably larger now that we're talking 64-bit) can fit in cache.

and with 2P bergamo it gets down to 195 threads per cpu..
