Seems filtering is your point. I do some filtering, but not very
complicated one.

Having no problems with CPU utilization, I have much more unpleasant
problem with cumulating memory leak.. :(

So, having 6M of free RAM at reload (after sucking in BGP-routes)
I loose 0.5M per day and forced to reload router weekly, otherwise
it became blocked, accepting no telnet connections, and need to be
power-cycled... :(

I tried to switch to 11.2.11 - it become even _worse_... I started to
loose 1M per day, so I rebboted router twice a week... Returned to 11.2.8
(sigh!).

I really wonder how it can be said something about GD on 11.2.12...
Miracles are good thing, but I do not beleive in them in ordinary life
and I can bet that this leak will not be cleared in period to 11.2.12 ;)
