in reply to number of open files Perl can handle

As ikegami has already alluded to, perl doesn't impose a limit on the max. number of open files - this is done by the underlying OS e.g. /proc/sys/fs/file-max on Linux, /etc/system on Solaris etc. etc.

Your OS docs &/or Google are your friends for further details...

A user level that continues to overstate my experience :-))
