I'm reading kernel docs and confused about the
cpu.cfs_period_us in this part:
3. Limit a group to 20% of 1 CPU. With 50ms period, 10ms quota will be equivalent to 20% of 1 CPU. # echo 10000 > cpu.cfs_quota_us /* quota = 10ms */ # echo 50000 > cpu.cfs_period_us /* period = 50ms */ By using a small period here we are ensuring a consistent latency response at the expense of burst capacity.
I'm not clear about the what's the difference if I "use a small period":
what's meaning of
ensuring a consistent latency response at the expense of burst capacity ?
