My load averages seem to be much higher than vmstat would indicate. I have ~100% idle, but load averages of 0.54. To me, 0.54 load average would be approximately (with 4 CPU cores, as my linode has) about 14% user+system+iowait.

Am I missing something here?

Code:
# uptime ; vmstat 5 5 ; uptime
 20:30:19 up 6 days, 12:46,  3 users,  load average: 0.54, 0.69, 0.54

In linux, load average is not the same as CPU load
