And you can configure the interval of vmstat updates freely.... Set the vmstat_interval to 60 seconds instead of 2 for a try? Is that rare enough?Not rare enough. Never is rare enough.Ok what about the other stuff that must be going on if you allow OS activity like f.e. the tick, scheduler etc etc.
Yes these are also problems... but we're either getting rid of them or reducing their impact as much as possible. vmstat_update is one member of the problematic set. I'll get you the detailed IPI measures, hold on... -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
