[ovirt-devel] [SCALE][RFC] ksmd bound to one core

[Sven Kieske]

Hi,

currently ksmd is a single process
and is thus bound to one core.

This leads to some scaling problems such as:

If you got a lot of vms on one host with huge amounts
of ram you can observe that the cpu usage by ksmd
goes easily to 100%.

I wonder if ksmd could not be split up
in child/worker threads, thus enabling higher density
of vms on one host.

or can this just be tweaked by altering values in
/etc/ksmtuned.conf ?

What do you think?
