here is short test:
without udelay:
# scp vmlinux  jso at patst007:/var/tmp/vmlinux-2.6.23-pa-d32up3
Password:
vmlinux                                                                                    100% 4364KB 101.5KB/s   00:43

with udelay:
# scp vmlinux  jso at patst007:/var/tmp/vmlinux-2.6.23-pa-d32up3
Password:
vmlinux                                                                                    100% 4364KB 436.4KB/s   00:10

well still far from what we could expect (about 800KB/s) but fwiw something supposing slowdown the kernel improve nic perf?
