I forgot tftp32 log. Here it is, starting from "default" file request:

[syslinux] PXEbooting very slow

I'm using pxelinux.0 version 3.81 
(3.80 had similar problems) with 
tftpd32.
It is very slow in loading 
"default" file; tftpd32 shows it 
continuously sends this file together 
with menu.c32, but pxelinux.0 
keeps on requesting for, say, 5 seconds.

Occasionally it is also slow 
in checking the other possible config 
files (those based on mac 
address): it spends some seconds on each 
entry.
If you have any test to 
suggest me to solve the problem, I'll 
try them and post results. 
Meanwhile I'll revert back to 3.75
Thank 
you
Paolo Franchetti
