OK, check the performance using 'ttcp' to verify that you are not seeing

I ran nttcp 5 times and here is what I've got:

Maybe it was not very good time for testing, because we had some troubles with network (as I understood
related to connection of new users) and my download speed fell to 100kb/sec (from server).

P.S. Today I tried new 2.4.22 kernel and there were no difference in performance.
