Dear Mike,
Did you check whether setting min_- and max_interval e.g. as per
https://lkml.org/lkml/2015/10/11/34
would help with your issue (instead of your "horrible gs destroying"
patch)?
Cheers, Paul

You mean you chose not to reproduce: you persisted in pinning your
perts, whereas the problem was stated with un-pinned perts (and pinned
oinks). But that is OK... others did reproduce,

You mean you chose not to reproduce: you persisted in pinning your
perts, whereas the problem was stated with un-pinned perts (and pinned

Dear Mike,
Did you check whether setting min_- and max_interval e.g. as per
https://lkml.org/lkml/2015/10/11/34
would help with your issue (instead of your "horrible gs destroying"
patch)?

Dear Mike,
You CCed me on this patch. Is that because you expect this to solve "my"
problem also? You had some measurements of many oinks vs many perts or
vs "desktop", but not many oinks vs 1 or 2 perts as per my "complaint".
You also changed the subject line, so maybe this is all un-related.

Dear Mike,
You CCed me on this patch. Is that because you expect this to solve "my"
problem also? You had some measurements of many oinks vs many perts or
vs "desktop", but not many oinks vs 1 or 2 perts as per my "complaint".
You also changed the subject line, so maybe this is all un-related.
