A bit faster doesn't help; you need wholesale improvements - an order of magnitude or better - for it to really get the install flying. As it happens, using gzip is typically 10x quicker. (Which translated into roughly a factor 2 improvement in install times when I tested it.) (bzip is so much of a bottleneck that it isn't really worth optimizing the rest of the process until you've got bzip out of the way.) -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/
