Performance netvanta 1335 utilizing nat and access-lists

Currently we have netvanta 1335 connected to internet utilizing 7mb/768kb adsl.
The netvanta 1335 is utilizing nat and access-list which means all is punted to processor.

CPU is running at 40 to 50% when circuit is busy

We are think of upgrading circuit to cable wideband of 35mb/2mb

What are the throughput capabilities of 1335 in mbits/sec and packets/sec when all is punted to processor

Trying to figure out what we will have to upgrade to

Thanks

Given the varying packet sizes, router configurations, and other variables at play, we don't publish specific throughput numbers - it's just too subjective. However, I can tell you that we do not recommend the 1335 for any application where process-routing would exceed 25Mbps in total.  In your case, 35Mbps down/2Mbps up would total 37Mbps and would exceed our recommended limits. You would be better served to separate the router and switching functions and go with a dedicated router like our NetVanta 3430, which has a recommended limit of 60Mbps.
