sure i did... maybe i'm misreading it
avg-cpu: %user %nice %sys %idle
16.79 0.00 26.39 56.82
Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn
dev8-0 11.80 2.24 184.95 541354 44609586
dev8-1 11.80 1.67 184.95 403090 44609586
Unless I'm mistaken the summary says that (on average) he only has 2
reads/s vs 185 writes/s

That's why I suggested he run iostat when the system is under more load.

The reason I think memory is no problem here is:
Mem: 3229040K av, 3166372K used, 62668K free, 0K shrd, 148480K
buff
Swap: 513976K av, 0K used, 513976K free 2758060K
cached
so the swap file has not been touched and there is 2.7gig of disk being
cached in RAM
