Subject: [pve-devel] auto ballooning && ksm thresholds both at 80%
Date: Thu, 30 Dec 2021 10:47:12 +0000 [thread overview]
Message-ID: <ee3aacec76017c117f04614494cfb79fdbc740d6.camel@groupe-cyllene.com> (raw)
Hi,
I'm still working on ha manager ressource aware && loadbalancing (I
have some big improvements to send soon before review)
I currently looking at memory balancing doing a lot of tests,
and I wonder if auto-ballooning threshold shouldn't be a little bit
bigger than ksm.
Currently both are at 80%,
that mean that ballooning is vm reducing memory fast, and ksm don't
have time to run.
as ballooning is a lot more intrusive than ksm, I wonder if it couldn't
be set to something like 90%.
Like this, ksm can try to keep memory at 80%, and if memory is growing
too fast up to 90% or if ksm can't really deduplicate pages anymore, we
have ballooning in action.
What do you think about it ?
