database worries

we really need to get the new memory for stan soon (they shipped it today I think, finally). once stan's up and can handle web requests, i want to get kenny being a read-only slave db server. it has nice scsi disks, and is the fastest of all the machines. it'll still do img.livejournal.com and ftp.livejournal.com also, and be the primary place where i login, tweak code and administer things.

cartman's the main bottleneck lately... database is locked way too often. the load's about 8.... CPU pegged. too many reads and writes.

also, I need info from you guys about the large file support.... that's going to be an issue pretty soon here:

Cartman is linux 2.2.18, glibc-2.1.3, ext2fs. Can that do LFS?
Kenny is freebsd 4.2-stable.... Can that do LFS? I think it can.
