--- Comment #6 from Mel Gorman
(In reply to Mel Gorman from comment #4)
It is possible this was an oversight. I do not have the full picture of what was planned but it appears that the intent was to activate this only for new containers. It's just the case that in Tumbleweed that normal sessions (or at least ssh sessions from root) are also impacted. If only processes within a container or a VM were resource controlled then it would limit the impact of this bug.
I think the intent was to really activate this for 'root' user sessions too. Regular user sessions are left alone for now unless unified hierarchy is supported and used by the kernel.
This means that any process launched by root be it manual launch of a server or a benchmark is going to be throttled. It cannot be what they really intended or if they did, it's a massive overhead to occur for very little, if any, gain.

The commit to me seems to say that it was only intended to be activated for containers :( -- You are receiving this mail because: You are on the CC list for the bug.
