HELP I NEED ADVISE ON CHOOSING ANOTHER ROUTER ??
I am working with a client who has a CISCO7201 which is at 100% CPU with 131,000 nat sessions.
7201: dies at 100% CPU, drops packets, end users see little or no traffic,
I replaced the 7201 with and ASR1002 with ESP5 and it is not much better.
ASR 1002: limping at 85% RP CPU, 62% SP CPU, drops packets, end users see 30% of actual plan speed.
The ASR is currently running at 83% RP CPU, 63% SP CPU with
WHAT ARE THE RECOMMEDATIONS AND ADVISE HERE, THE ASR1002 ISNT MUCH BETTER

When it comes to strict scaling, the ESP-5 is targeted at about 250K NAT translations, the ESP-10 is targeted at 1M NAT translations. I assume there are times when you end up above the level shown in the output above given your description of the level of CPU utilization. Here's a doc for reference:
The "Security" Section shows NAT translations on each ESP. Hope that helps.
