Hi Ian,
Is that a TCP test on iperf?
Yes, that was the result of a TCP-test on iperf.
Also make sure you are using a modern enough version of iperf. Some
versions needed a patch to work correctly with some versions of the linux
kernel.
Try again using UDP,
I did, there I reach 32Mbit/s in both directions.
it may be the long fat pipe issue

Thanks, I'll check that :)

Subject: [c-nsp] PA-E3 in 7204VXR - low bandwith
Hi everybody,
a customer connected with a 7204VXR (NPE-225), PA-E3 has bandwith-
problems. The maximum outgoing TCP-throughput amounts only 15Mbit/s
instead of 34Mbit/s (measured with iperf from the customer-side:
[ 5] 0.0-10.0 sec 17.4 MBytes 14.6 Mbits/sec
Incoming bandwith is ok:
[ 4] 0.0-10.1 sec 39.1 MBytes 32.3 Mbits/sec
There are no rate-limits configured, there are no errors on the
interfaces
itself, the 7204VXR is pretty underutilized - so everything seems fine
from
that point of view.
Any Ideas?
Regards,
Werner
