in thread Solution to broken Net::Ping
If you're concerned about performance, Benchmark it, not against some production host. What works for me under my current environment, may not be the best way for you under your constraints. A general solution to monitoring availability of hosts is non-trivial. And make sure you're not optimizing prematurely.
The last time I was mucking about with ping, it was on a large scale internal network and I ended up using SNMP gets instead. If you usage needs to be efficient, you might want to look at Net::SNMP as well.
