Some advantage in prefork several imapds in startup ?

[Lucas Zinato Carraro]

In tests,  i configure /etc/cyrus.conf  to start 5000 process in startup.

SERVICES {

        imap            cmd="imapd"    listen="imap"  prefork=5000

}

Consulting the system:

imap_server:/var/lib/imap/proc>ps axwww | grep imapd | wc -l
5177

But in: ls -l /var/lib/imap/proc  | wc -l  i see only
173


Why, the master start new  process and don't use  prefork  process ?
Exist any advantage startup with several process ?

Zinato
