I think best you can do is buy 'network programming' by Lincoln Stein. Read it cover to cover and then start writing your daemon.
It covers everything from basic network programming to multiplexing, threading and forking for high loads.
It also covers 'daemonizing', logging and other stuff you probably want to do.
In short: A perl program can perform well under high loads, it can even perform better than stuff written in other languages.
I'm longing to hear Marc Lehmans talk at German Perl Workshop, why he wrote his own web server for very high loads that couldn't be served by apache and thttp.
