is an alternape LWP::UserAgent mechanism, but I'm not sure about the benchmarks. It looks pretty small, so it should be pretty quick.
However, my advice is to check your bottlekneck first. Are you sure you own bandwidth isn't limmiting you? If you have a 56k connection, and are downloading a 200kb file, then that's probably the real problem. On the other hand, it's possible it is the module, and I guess I'd use one of these two (I'd adapt Bio::Root::HTTPget, personally.)
