Thomas,
Depending on the number of threads within your processes (and what they are doing) you may need to break things out some more. The other thing to look at is turning ‘translation throttling’ on for all the processes in that site. Depending on your volumes, the engine may be spending all of it’s time getting messages and Xlating (yes, even ‘raw’ uses the translation thread) that it can’t finish moving things out.
