Considering > the low overhead of tftp, and how much I use it (bootp), having this service > kernel-based would be a step forward here .... I don't think so: - TFTP is policy. Policy belongs to userland. - Kernel servers aren't any faster than userland servers. The X15 webserver showed that it is possible to write a userland webserver that is as fast as the record breaking TUX kernel webserver. - TFTP clients are usually bootloaders with TCP stacks tuned for being small instead of being fast. Having an exceptionally fast tftp server won't speed up the boot process. - TFTP is only done for booting a system. Booting doesn't happen to often, so optimising that part doesn't help you much. Again, if you still think you have a bottleneck over there, you can expect to gain much more by tuning the TFTP client. Erik -- J.A.K.
