Ok. I have checked this. Almost all of the TUX processes are in S state.

apache    4753  0.0  0.0  3424  764 ?        S    15:26   0:00 [TUX
worker 0]
apache    4754  0.0  0.0  3424  764 ?        S    15:26   0:00 [TUX
worker 0]
apache    4755  0.0  0.0  3424  764 ?        S    15:26   0:00 [TUX
worker 0]
apache    4756  0.0  0.0  3424  764 ?        S    15:26   0:00 [TUX
worker 0]
apache    4757  0.0  0.0  3424  764 ?        S    15:26   0:00 [TUX
worker 0]

But still my load average is about 2. What does this mean? This machine
is dedicated to TUX server btw. The traffic is pretty huge, about 4
million pageview / day. 1 page has about 10 images, so it is about 40
million access to the images.
