Hi Massimo,

As posted at

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.

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 :)
