With this one on a 32-core system, I get:

glimpse:
real    0m6.549s
user    0m49.136s
sys     0m3.076s

idutils:
real    0m6.749s
user    0m51.936s
sys     0m3.876s

gitgrep:
real    0m6.805s
user    0m51.572s
sys     0m4.432s

coccigrep:
real    0m16.369s
user    0m58.712s
sys     0m5.064s

I redirected stderr to stdout, and verified glimpse output has:

glimpse request = request_threaded_irq

Does this match expectations?
