Hello all!
I remember being able to reach 11-12Mbytes/s between two Win95
workstations with NE2000 $10 NIC's installed, connected via BNC cable.
I am now able to reach 11-12Mbytes/s between all kinds of Windows
2000/XP machines with all kinds of cheapest 100Mbit ethernet hardware.
But I have never ever exceeded 8-9Mbytes/s between a Windows machine
and a FreeBSD box - _never_. Be it Samba, different ftp/http servers,
FWIW... I recently had reason to investigate a network's performance. I
was able to consistently get ~95% throughput from windows machines to
FreeBSD boxes. I was using iperf (there is a WinX version of iperf as
well) and chargen for testing. All PCs were old, and generally using
cheap onboard NICs
Might try tools specifically geared towards throughput testing. Various
protocols have varying amounts of overhead. Tools with throughput
testing in mind obviously have overhead minimized.
Just my .02 cents.
different FreeBSD versions (4.x/5.x), with ipfw enabled or disabled,
etc., - the speed always hovers around 7-8Mb/s. I know it's not
critical, I know I should've upgraded to Gigabit hardware long ago,
but is there something wrong?
I tried different linux distros, but they all seem to be even slower.
Wazzup?..
Thanks,

Here is the "ifconfig" output from a machine that has one nic set at
10Mbit/half duplex and one at 100Mbit full duplex. how does it compare with
your system?

.02 more cents.....
Sometimes autoselect can work against you. Might try tying it down.
