Please help! Slow gigabit on old machine
Hi,
Have upgraded my Dell Dimension 8200 (from 2002) 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.
Can the fact that the pc is old affect things that badly? I expected about 800,000 Kbits/sec throughput?
Can anyone advise where should I look now?
Please help!!
thanks!
David

Many times older hard drives cannot keep up with Gigabit speeds. Think of trying to drink through a fire hose. Your computer just can't handle it probably.
