Subject: [Iperf-users] Please help! Unexpected throughput for gigabit

Hi,

Newbie here, to iperf and much networking.

Have upgraded my pc at home to gigabit adaptor (Intel Pro/1000 MT) and was 
excited to hook up my laptop and run iperf to see the awesome 10x speed 
increase ;)

With 100 mbps I averaged approx 30,000 Kbits/sec.  When I reran with the 
gigabit PCI adaptor, I only got up to about 90,000 Kbits/sec.

I really need some help figuring out why!  I have checked cables and they are 
Cat6 or Cat5e.  The router is a high end Netgear (WNDR3700v2) and the lights 
show green (gigabit).  The laptop connection shows gigabit, as does the pc.  I 
ran all the tests that come with the desktop adaptor, and they all pass.

This is an old PC - 2002 - Dell Dimension 8200.  Can that affect things?

Where should I look now?

Please help!!

thanks,

David
