Running multiple perlbal instances

[Kevin Olson]

Does anyone have some advice on running multiple perlbal instances on one
multi-cpu box?  We're getting to the point where one perlbal instance is
handling 30,000-45,000 connections/min and load is hitting 1.00.

An easy solution would seem to be to have different perlbal instances
handling different vips, but that introduces extra config files and what
not.  It'd be nice to simply round-robin load balance between the two
instances, without adding another full blown load balancer to the mix.

Any suggestions,warnings?

Thanks,
