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

Also 3.75 sometimes "hesitates" a bit, but it's faster anyway, and
has
quite constant delays.
Machine is an Acer netbook with Atom N270 and a 
Realtek 8102e ethernet card.
Server is tftpd32 ver 3.10beta(last 
version working on Win98)  on Win98. It seems that tftp32d ver 3.33 on 
WinXP doesn't have the problem, but I will check again and make other 
tests, when I have time
Thanks for the pre-releases link, otherwise I 
wouldn't have found them. What is git bisect? How do I make it?

If 3.75 works for you, it would be extremely interesting if you could

Any news on this?  If "git bisect" is too complicated, it 
would at least
be useful to know which prerelease, if any, introduced a 
problem.
