6.2+pf+CARP bandwidth issues

[Eric F Crist]

Happy monday folks!

We have a couple of Dell PowerEdge 1650 systems in a CARP setup with  
pf as our firewall cluster.  I've noticed that if I connect my laptop  
behind these systems, I can achieve about 600kbps down and about  
1100kpbs upload.  If I connect to the other side, bypassing these  
systems, I can achieve our entire bandwidth cap provided by our  
colocation company.

What things should I look for as far as tuning goes?  Any gotchas I  
should look out for?  All the interfaces and switches in question are  
gigabit.  Some interfaces are fxp, others are onboard em.

Thanks for you replies!
