I have noticed that whenever ubuntu Firefox is "trying" to get some
data, it sucks up 100% of the CPU. I don't notice the same behavior
under Windows. The implication of that behavior is that instead of
waiting on a socket, it's sitting there doing some kind of a busy wait
loop. It would be interesting to see if the same behavior occurs with
other applications and if it does, that would imply the problem is
further down in a library or kernel subsystem.
The only other time I've noticed significant resource consumption is one
flash is in operation. Sometimes I have pages with flash that just
consume all the CPU available and don't go away until I kill that tab.
