Hello,
We have a new 100mb WAN installed from the UK to Germany and it seems very slow, so I'm after any advise. I've used these iperf commands:
Client
iperf -c 172.30.0.100 -t 100 -i5 -P 10 -b 11m
Server
iperf -u -s -i5
Results from Uk to Germany PC

It starts off ok then drops down:
When testing from the opposite direction so from Germany to the UK it is ok. I test copying a 224mb file from the UK to Germany and it too 25 mins, but the other direction it was 4 mins.
I tried the same test to a different office on a 2mb SDSL line and the 224mb file took 17 mins to copy and the same test again took 60 secs to another office on a 20mb line.
Our WAN provider manages the Cisco routers but I have access to get any info. I'm just trying to prove to them that something isn't right. I think this coudl be the start of a long journey
Thanks
