Summary ⇒ Filehandle and process limit on redhat

I ssh in parallel to all the other systems.
But because the limit of processes and open files is very low (100 and
200) I can only run very few jobs in parallel.
It is fine to keep the soft limit where it is, but it would be nice if
the hard limit was much higher. So that you can raise the limit if you
know what you are doing.
On most of my systems I have 1M file handles, and I do not experience
any performance or memory issues due to this.
So the adjustment is for nofile and noproc in /etc/security/limits.conf
These seem OK: /proc/sys/fs/file-max /proc/sys/kernel/pid_max
