If I remember correctly procfs is off by default
for security reasons.

procfs is for user land applications, the kernel obviously
has other means to examine running processes.
I doubt that mounting procfs (without using it) has any measurable
effect on the system's performance, but if it does, I would assume
that it decreases performance rather than increasing it.
