Basically, if you want to send something to the network, the kernel has to copy your data to its memory space. It is an overhead and with these patches, the kernel doesn't has to do it. So it is faster. Moreover, few ethernet cards are able to compute the ip checksum so linux doesn't need anymore to do that. -- Mathieu CHOUQUET-STRINGER E-Mail : mchouque@e-steel.com Learning French is trivial: the word for horse is cheval, and everything else follows in the same way. -- Alan J.
