This would not actually help much as still each received update has to
be analyzed separately.
The grouping is important for egress policies - all BGP peers with the
same egress policy would be placed into the same BGP update group
dramatically reducing processing of outgoing updates.

Why a route-map PER peer? Can you not group them under the same
conditions
and simplify things a bit?
This may not be the problem .... sounds like something else possibly..

I feel desperate: I just turned up a new Transit Session with an
upstream and my router goes nuts and is dropping other BGP sessions on
it: 4/0 (hold time expired) 0 bytes
The situation is like this:
The router is peering on a public IX with approximatively 150 members.
Each BGP session has its own route-map, so the list is really BIG!
When I turned up my transit about an hour ago, CPU went to 100% and is
still at 100% right now and it drops BGP peers and brings them back,
and drops and brings them back, ... I'm in a loop and I think the only
way to get out of that look is to bring up each bgp peer step by step
- really not an option.
CPU utilization for five seconds: 100%/5%; one minute: 99%; five

What is eating my router's CPU?
Is it the big list of route-maps?
