Slow speed through 1710

Hi there

We have 2 1710 routers and both seem to he very poor throughput. I realsi that one interface is only 10Mbps but we are only getting sustained transfer rates equivalent to 2.4Mbps through each router. When I view a graph of the port utilization while doing a large file transfer I can see that the ethernet0 port peaks from time to time at around 10Mbps but keeps dropping back to 0 every few minutes - it is this drop down to 0% utilization which is affecting the throughput I think (as opposed to max throughput not being high enough).

The routers are between our DMZ and 2 private networks. They both take part in VPNs. One is a site to site VPN and EZVPN server (for 2 different VPNs) and the other is an EZVPN client. When I deconfigure the VPNs there is no increase in performance.

Does anybody have any ideas about improving the performance or is this the best I can expect from a 1710?

Thanks - config to follow:
