It is several times slower for decompression as well, and requires a lot more memory than gunzip (even in low memory, low speed mode). On a fast machine bunzip2 decompresses at about 500K/s (or 250K/s in low memory mode) while gunzip gets 3500K/s, so while it would speed up most net installs it would slow down a CD install. > > > > In my experience this is correct. www/lynx-current is one candidate for this - > > the distfile is about 1.3M compared to 1.7M. > > Just make sure the new releases of FreeBSD include bzip as standard then.

And which one will be the default: bzip or bzip2?

Bzip2 replaces this with Huffman coding. -- csubl@csv.warwick.ac.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
