pidof and pgrep are slower than a grep /proc/[1-9]*/comm

Hi,
just for your information:
pidof $string
pgrep $string
are sensitively slower than this one
fgrep "$string" /proc/[1-9]*/comm | cut -d/ -f3
in particular when taskset -pc 0 $$ is used, but also in general.
I can accept that my system is the root cause of this issue. Moreover,
it is not the only anomaly that I have noticed.
f() { local pippo=$(command1) ; echo $pippo; }
is sensitively slower than
f() { local pippo; pippo=$(command1) ; echo $pippo; }
Best regards, R-
