[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
