netstat -n

Yeah, that is the one that lies to you.

but the problem about throuput going from 45 to 135mbps is not normal.

Well, actually it is. That can be caused by a lot of things. The usual cause is bandwidth shaping, by internet suppliers (not necessarily your own).

Under windows, I have a very stable 192mbps throuput during the test time (nperf) each time. (with or without IJFW, the fluctuation is the same and changing the driver, not working better.... tcp/ip ?

As I said, there are a lot of reasons for the speed to fluctuate. You can do a test between two systems, on your own network, to see what happens (eliminating outside influences). There is a program, called netio, at Hobbes: http://hobbes.nmsu.edu/download/pub/os2/util/network/netio132.zip. It will work between two computers, and it has support for more than one OS. If that shows the same thing, you need to look at your own setup. If it is good, you need to look outside of your own systems.
