Kprobe2 performance

Hi all.

Are kprobe scans affected by system resources? Like if I listen to music & do some browsing at the same time…


The amount of samples can be affected by system speed and by how much CPU time is available for KProbe2. The slower your system speed and the less CPU time available, the more samples will be dropped by KProbe2. When samples are dropped, the total amount of reported C1/C2/PIE/PIF will be lower.

So if you use your system heavily while running a KProbe2 scan, the reported error counts will be lower than normal.
