Expected throughput for one wired connection?

[hay7777]

Hi,

Newbie question...

Got me a WNDR3700v2 router, with desktop with gigabit pci card, and laptop with gigabit wired connection.

New to testing network speeds etc, and downloaded jperf after reading about it on here. I have both laptop and desktop hardwired to router with Cat5 cable and I run jperf with 1 parallel stream.

I was suprised to only get a throughput of about 55000 Kbits/s.

Is that to be expected? It's a old desktop - would that have anything to do with it?

thanks for any help...

Even with old equipment, you should get > 100 Mbps. Be sure that the adapters are both reporting Gigabit connections.

Try using file copy of a large file instead of iperf/jperf. You can get very different results from iperf/jperf depending on the settings used.

Hi,

Thanks for the reply. I ran a loopback test on both laptop and desktop - the laptop result was approx 400 Mb/s, the desktop only 30 Mb/s.

It's a Dell Dimension 8200 bought in 2002, Pentium 4 1.9 GHz machine with 512 MB RAM (it's the old RDRAM type which is crazy to upgrade).

I also ran LAN test which copies a file across, and I get approx 35 Mb/s write and 55 Mb/s read.

Is there a way to help the desktop, or am I stuck with the poor performance due to the weak machine?

thanks,

David

Nope and yup.
