Re: [OpenSBC] poor performance of opensbc

[Joegen B. <joe...@gm...>]

What you are seeing is the experimental pike mechanism which limits 
registrations to 5 CPS to augment a potential DoS attack.  This is the 
reason why CPU is at normal level.  I have recently disabled this in CVS. 
Can you try CVS head if you still encounter this problem?
