32 servers each have 2 Perl daemons running - 16 of them have one port
forwarder (which also does limited data validation) and a collector
which soaks up UDP packets; another 16 have a pair of Perl daemons, one
to transfer data from other nearby servers and a second to do the actual
munging. In addition there's an analyzer farm each of which has a shell
script daemon acting as job scheduler running Perl scripts on demand.
There's a database server with half a dozen assorted Perl daemons and a
chunky NFS server with mixed shell and Perl daemons.

I'd use Perl for proof-of-concept if I could, but rewrite in something
else for a production system particularly if any kind of performance was
needed - Perl/tk ain't fast :-)

Dead right. Frex, Java wouldn't handle the volume collection/munging
system mentioned above (for memory requirement and performance reasons
mainly).
