I got used to rsync's -v --progress option so much that I used it instead of rcp even to simply copy files across the network. I dont like software that doesnt talk to me! :-) I like the percentage bar that --progress gives! To my surprise, I found that, when dealing with 1GB+ files, rsync is 4-5 _times_ slower than rcp. Yes, I know that rsync is optimized for sending deltas to a file

Well, maybe this is sort of related... Eric Raymond has written an article for the Linux Journal on how to build an Ultimate Linux Box. You can find the whole thing at http://www2.linuxjournal.com/cgi-bin/frames.pl/articles/style/0014.html The machine is said to compile the Linux 2.4.9 kernel in 1 min. 50 sec. I wonder how long it might take to build R on this beast... Cheers, Andy >

Hi, I don''t know if this has been discussed before, but have you thought about adding LZO compression to ZFS? One zfs-fuse user has provided a patch which implements LZO compression, and he claims better compression ratios *and* better speed than lzjb. The miniLZO library is licensed under the GPL, but the author specifically says that other licenses are available by request. Has this
