(heading off towards a new topic, but hey, the sparc64 list needs more off-topic posts anyway ;-) ) In my tests it's not the CPU in the Ultra5 that makes buildworld slow, it's the IDE interface that must've been designed by Lucas[1]. Adding memory helps simply because it lets the file cache stand a chance, though I don't believe the buildworld process re-uses nearly as many files as, say, a production web server. There are two things I've tried to alleviate the slow disk I/O: * I tried using an Ultra SCSI card and drive. This helps immensely, but I needed the card for another box. * I mount /usr/obj, /usr/src and /usr/ports off another box. With a bit of NFS tuning, I went from around 2MB/s to around 8MB/s Seriously, by NFS mounting the filesystems needed to buildworld, I drastically speed them up as compared to local disk.

Collectors of classic British motorcycles will know what I'm talking about. Lucas designed electrical systems, including lights. They were often nicknaemd "Lucas, the Prince of Darkness" (a great pun) -- Real men use "cat /var/spool/mail/$USER | more" and "telnet $SMTP_HOST 25" - Anonymous Unix geek "more /var/spool/mail/$USER" <-- don't waste a process, you idiot - Second anonymous Unix geek
