This is something that has been bugging me about this whole thing.   If you are testing with such a small file, wouldn't that file be completely in the linux kernel file cache?  So the filesystem shouldn't really be making much of a difference at all.  Apache should be doing a straight sendfile out of the file cache buffers directly to the network interface?  If that is the case then it seems the target for issues would be the network driver subsystem?
