Hi, everybody,
I hope this is the right place that I post to!
When I enabled polling in 5.4 and 4.11, I found that CPU load
in 5.4 is much higher than 4.11. For example, suppose HZ is 5000, in 5.4
the idle CPU is about 87%, but in 4.11, the idle CPU is about 99.9%. Is
this right? Or the statistic is wrong in 4.11?
BTW, ACPI is disabled under 5.4.
BTW, I found that context switch in 5.4 is much higher than 5.4 while
enabling polling. (Using systat -vmstat 1)
I'm looking forward your reply.
Any response is welcome!
David.Mao
