High CPU load

[Simone Morandini]

Hello list,

we are running BIRD on our IXP peering platform with no problems since 
quite a while now.
We need to activate a new peer which is expected to announce a 
considerable amount of prefixes (~100k), and the first try resulted in 
having nearly 100% cpu load, ~60-70% for BIRD and the remaining for 
syslog. The machine was hardly manageable, so after a few minutes we had 
to disable the peer and restart the deamon.

The current settings actually make BIRD log everything:
log "/var/log/bird.log" all;
log syslog all;

so I guess we could start by modifying it: any advice on this?
Would you suggest something more, in order to avoid having again a high 
cpu load?

Thanks in advance,
Simone.
