Hello guys
After reinstalling my centos + cpanel, because its was hacked, now I'm more into security of my server. can somebody explain me what kind of processes are this and why they are consuming so much resources:

Yesterday:

user	domain	cpu %	process

gcc is your compiler installing things (form the install)
/usr/local/cpanel/bin/rebuild_sprites rebuilding your cpanel theme icons
/usr/bin/spamd self explanatory
/usr/bin/perl /usr/local/cpanel/scripts/ installing your Perl modules (also from the install)
