hdparm -Tt /dev/sda
/dev/sda: Timing cached reads: 1426 MB in 2.00 seconds = 712.73 MB/sec Timing buffered disk reads: 166 MB in 3.01 seconds = 55.09 MB/sec This is a bit slow, but nothing that should impact your performance that much.
echo 3 > /proc/sys/vm/drop_caches; time pacman -Qs foobarbaz; time pacman -Qs foobarbaz
real 1m45.235s user 0m0.127s sys 0m0.590s
real 0m0.097s user 0m0.043s sys 0m0.023s Can you repeat this and use /usr/bin/time instead of just plain "time"? You may have to install the "time" package. echo 3 > /proc/sys/vm/drop_caches; /usr/bin/time pacman -Qs foobarbaz; /usr/bin/time pacman -Qs foobarbaz
Once you do that (but please get the numbers first!), try running `pacman-optimize` then rerunning the above test. Finally, what is the output of df -h for whatever drive /var/lib is on? Is it near capacity? And what filesystem with what mount options?
echo 3 > /proc/sys/vm/drop_caches; time pacman -Ss foobarbaz; time pacman -Ss foobarbaz
real 0m1.299s user 0m0.200s sys 0m0.023s
real 0m0.252s user 0m0.200s sys 0m0.010s
At least this one is OK. -Dan
