Try setting a BPF for ignoring the SSH port.

Hello,

I am trying to SSH/rsync files between two subnets (10.2.x.x/16 and 10.20.1.x/24) snort is running in-line on the 
10.2.x.x subnet and not on the other.  What I am seeing is my rsync goes really slow and if I login to the snort box 
I see CPU at 90-100% pegged... if I stopped the rsync the CPU goes back to normal.

I have the SSH pre-processor stuff disabled and still see this behavior.  Does anyone happen to know what could be 
causing this?

Thanks,
Cody
