pacman lag

pacman lags the first time i use it after a boot, or if i haven't used it in a bit, say 30 minutes. i'll enter a command (ex. pacman -S xxxx), and it will pause for about 1 minute then ask for confirmation. the next few times i use it it's really quick to respond, and goes back to being laggy if i don't use it for a while.

Sounds like the old pacman (v2) to me. You sure you've upgraded properly?

pacman -V

No, this is actually "normal" - pacman uses thousands of tiny files on disk, which causes a decent lag the first time they are used, due to the disk seek time. Still, 1 minute is excessive - here the initial lag is only around 10-15 seconds. This *is* being worked on, but for now most people either
a) optimize the partition that pacman is on
b) throw some tricks at it

For (a), can you tell me what filesystem /var is on your system? If it's ext3, you can turn on dir_index and noatime on that partition, which will speed it up significantly.

For (b), you can do something like, add "pacman -Ss initializing > /dev/null" or something to rc.local, which will do that first load of all files when your machine boots... it's crappy, but it does work.
