Im a bit of a newbie when it comes to using IPerf and wondered if any of you can assist me.
Im using Iperf to test the available bandwidth across my companies WAN, so far its working fine using TCP.
I have two identical laptops, both running windows XP 2 with the following spec.
centrino 1.6 mhz
512 megs ram
5400 40 gig HD
supposed 1 gig NIC.
I have one laptop into a switch located at the far end of our network, it is passing through a firewall and the route between the two laptops runs across at least 5 diffirent subnets.
The command im running on the server is;
iperf -s -u -p3001 (for UDP testing)
iperf -s -p3000 (for TCP testing)
On the client laptop im running the following commands;
iperf -c 10.X.X.X -u -b 95M -p 3001 -i 1 -t 60 (UDP)
iperf -c 10.X.X.X -p 3000 -i 1 -t 60
Now as I said the TCP command works fine but when I run the UDP syntax I only ever 49 mbps or there abouts, any suggestions?
Also a major head ache is gigabit bandwidth testing.
Now the laptops claim they have gigabit ethernet when your connect them directly (using windows XP), however when I run iperf using the above mentioned commands I get no more than 180 mbps throughput.
Now I seriously doubt that the NIC interface to the laptop bus (the card is built into the motherboard) has a transfer rate of upto 1 gigabit... but im not sure.
Ive had a look through google on how to configure windows XP for gigabit ethernet but its gone way over my head, I do not fully understand slidding windows and the like.
Is there a good guide out there of what to change in order to get this working, or at least increase the speed from 180 mbps?
A colleague of mine suggested a linux build as he claims the TCP IP stack handles gigabit ethernet better, is this also true ?
Thanks for any help you can offer.
