Hi Massimo,

I say go here as a means to try to get data on your connection.

What does it say your "RWIN Scaling (RFC1323) = 2 bits (scale factor:
2^2=4)" is?

and what value does it give for "Unscaled TCP Receive Window"?

"Unscaled TCP Receive Window" is important because this
maybe the maximum tcpswinsize/tcprwinsize values you that
you will be able to use if a multiple does not fit in or under
the OS/2 maximum of 246723. Putting a number in without
it being a proper multiple will result in retransmits.

What you are looking for is a MULTIPLE that fits, the size of RWIN is not

overly important for us. Ignore the bandwidth * delay product for now. If

you are interested you can find more information on that by searching for

RFC1323 and having a read.

Feel free to post everything in the window from that webpage
in the "Share Your Results" box.

i will be forced to move my firewalls from eCS (or AOS in the future)
to applicances :(

If you want to get the full speed of your line, you may not
have any other choice.

Life would be easier if we had TCP/P Autotune like Linux has
but we do not :)

Cheers
