Re: What's the progress of per cgroup background reclaim?

Hi,

2012/3/16 Ying Han [off-list ref]:

Thank you for the information.

Sounds like that is exactly what the per-memcg kswapd was designed
for. Two things I am interested to looking into now:

1. why the per-memcg direct reclaim introduce such noticeable latency
spike, what workload that can reproduce that?

Sure, I will look into this this week.

2. we can quickly patch the last version of per-memcg kswapd (V6) on
your environment and see what difference it makes. Maybe I can help on
that.

Thanks a lot.

Thanks
