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.
