Thus spake "Mark Kent" <mark () noc mainstreet net>

another thing is you will see increased latency and jitter as your
packets
individually queue for cpu process time

Thanks, that statement is significantly different than:

1) That is very deadly
2) If you want to crater your router, sure

both referring to "no ip route-cache"

I was just pushing for more moderate statements :-)

We were assuming he was actually pushing traffic, not using the router for a
doorstop.

An NPE-200 should push around 200kpps (no features) using CEF; that drops to
less than 15kpps with process switching.  Lowering a router's performance by
over 90% qualifies as "cratering" in my world.
