Hi, output of vmstat:
# vmstat 5 procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 2 13 100 10448 232800 331344 0 0 208 1180 43 84 8 23 4 66 0 13 100 9116 232812 331332 0 0 246 465 384 357 0 1 0 99
What are these 13 processes? What do they do? Post output of "netstat -anp". Googling around about tuning SATA drives keeps coming back with What makes you think that SATA is the bottleneck? but as far as I understand much slower buffered reads than I should expect:
Timing buffered disk reads: 2 MB in 3.16 seconds = 648.12 kB/sec I can't take the system down to single-user for testing, though, so I'm not sure how meaningful are these numbers.
On busy machine they are meaningless. -- Arieh
