Probably so, but this demands that the entire contents of you webspace
(or at least the active part) can be fit into the RAM cache.

And if this is the case, the local file system should be able to cache
just as well. With Tux you would be able to take better advantage of the
zero-copy sendfile stuff in the linux 2.4 kernels, letting the network
card DMA the data straight from the filesystem cache (as I understand
it). Don't know if AFS is able to do that.

I may be mistaken though.
