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
