Hi Community,

I am currently trying to find out whre and how my network is limited and I got strange results, which I don't really understand.
First I used iperf between two windows 7 machines on GB LAN and got following results: Shocking...

But when I copy files between the two windowses I got reasonable performance (the receiving PC is just a Atom 330)
Anyone has an idea, where the difference comes from?
Or am I just using iperf wrongly? (iperf -s on server and iperf -c IP on client)

Thanks for your help,

Crowi

by the way, I get similar results with iperf and copy to and from the NAS.
I.e. when i set the NAS iperf server or client, I get between 200-300 MBit results, but copying to and from the NAS with W7 PCs gets me ~80MB/s
:-/

try do same test but using 64K windows size (you simulate a copy of Big ISO files):

iperf -c 192.168.178.25 -w 64K

Hi Raulfg3,

seems you saved my life, once more
Thank you!
Looks better now...

Now I have to get it up to 900MBit/s, hmmm, how?

Cheers,

Crowi

and from win PC 2 to NAS

So and thanks to Raulfg3 and iperf I identified my LAN bottleneck

here's the latest result and I am happy with it:
I bypassed the GB router/switch/ap (which was connected just between my two main LAN lines) with an left-over switch, that's it...
Problem solved
