This is particulary true if your logfiles are stored on a different machine, 
and are accessed over the network. You'll see a huge performance boost if 
you zip the logfiles first. But make sure that the zip process runs on the 
server that the logfiles start on - there's no point in sucking the files 
across the network to compress them.
