Hi,
commit 2f46993d83ff upstream.
Please backport this commit to the other stable kernels, since this patch landed on 6.1 and We've seen 30% improvement with docker containers running heavy cpu/mem tasks

Why is this required at all? It just changes a default option, you can set the "faster" option yourself if you really feel it is a good idea for older kernels, why can't you do that for containers you want it enabled on for these older kernels?
And what exact kernel versions did you test this on?
And how is this not a new feature?
thanks,

The patch has already motivations of why this is a better default, and changing this would give performance improvements
And what exact kernel versions did you test this on?
this was tested on 5.15 and 5.10
And how is this not a new feature?
As you mentioned it changes the default option, Why is this considered a new feature?
thanks, MNAdam

Changing the default option when booting is a new feature in that it changes what was previously happening before.
And, anyone running those old kernels, if they are comfortable with making this feature the default, in order to get the performance increase you say is there, can change their command line to do so, no kernel changes needed.
So for now, I'll leave this as-is, thanks.
