I'm noticing too slowly on the vty lines. Does anyone know which may be due and how to fix?
Doh, my bad. My eyes read "vty". My mind registered "console". Please disregard my previous post.
So do you experience the slowness through the console as well, or only via SSH?
Is this new router configured to use any external AAA backend, such as TACACS or RADIUS? Can you post the "show version" and relevant bits of AAA configuration, if any?
Can you post the output "show proc cpu sorted" while it's slow?
