Hello Ken,

looking at your configuration I see

ip route 10.0.0.0 255.0.0.0 10.1.1.0

but your internal interface Vlan1

interface Vlan1

description $FW_INSIDE$

ip address 10.1.1.1 255.255.255.0

so IP next-hop of that static route should be an IP address like 10.1.1.x

with x <>0,1, 255

you haven't implemented a VPN up to now but you have deployed a zone based firewall.

This has an impact on performance.

I cannot dig on the details of zone based firewall you have configured with SDM.

However, it can impact on performance of this small box.

is the other device configured for just routing ?

Hope to help

Giuseppe

Giuseppe,

I wanted to thank you for your reply.. I greatly appreciated it.. I changed the route statement and saw an improvement in performance but was still slow so I started removing SDM policy maps and cleaned the config up to the basics and performance is what I anticpated it should be. The added configuration significantly degraded performance. Thanks again!!
