Dne 29. 06. 21 v 22:25 Ben Cotton napsal(a):
When this proposal is implemented, they can instead declaratively
specify the amount of RAM needed per build thread, e.g.

   %limit_build -m 8192

for declaring a build thread should be allocated 8GB of RAM.

Do I understand it correctly that semantics will be: One process will consume 8GB ram. And because we have only 16 GB RAM on this host we will limit smp flag to 2 despite having 4 cores. Right?

FYI Copr utilize heavily tmpfs plugin

we have ~100 GB swap which we use for tmpfs.

This can provide misleading numbers for SwapTotal.
