Hi!

I think there is a serious TCP bug(s) in RELENG_2_2.
TCP input rate is ok (800-900 Kb/sec).
TCP output rate is TOO SLOW (approximately 30 Kb/sec).

OS: 2.2.1-RELEASE,
    2.2.2-RELEASE,
    2.2-STABLE kernel (1997/07/19)

Ethernets:
    3Com 3c579 ("ep")
    Intel EtherExpress Pro/10 ISA ("ex")
    Intel EtherExpress 16 ISA ("ix" on 2.2.1, "ie" on 2.2.2 & 2.2-STABLE)
    NE2000 Compatible Card ("ed")

In THE SAME network configuration there is NO problems
with 2.1-STABLE (1997/02/26).

The cards I've tried with 2.1-STABLE are: 3Com 3c579 and NE2000.
Both the input and output rates are approximately 850 Kb/sec.

TIA
