Reaaly slow means 5-6 minutes to move an 4 MB file from one computer to
the other...
I used t o do it before and it used to take few seconds...
Computer are two Athlon XP 1600+/XP 2000

Power is more than enough...

I guess is some network configuration that gives us problem. I'll try to
change all the settings on both the computers...
Any idea to debug the problem?

In the meanwhile.. I'll have a look at the processor time as you
suggest.


Thanks
Alessandro
