WebAttempt to throttle perf’s sample rate to this percentage of CPU. Note: the kernel calculates an “expected” length of each sample event. 100 here means 100% of that expected length. Even if this is set to 100, you may still see sample throttling if this length is exceeded. Set to 0 if you truly do not care how much CPU is consumed. WebDec 18, 2024 · If all threads in a cgroup stop being runnable on a particular CPU, such as blocking on IO, the kernel returns all but 1ms of this slack quota to the global bucket.
