OK, I think I know what is happening.

I am running my test instance in a VMWare host and the disk IO is poor.
Because there is a type of flow-control in place due to the multi-threaded options
even when not enabled, if there is a destination to disk of the incomming data stream, the
source is not read until the output can be flushed. This made all of my tests dependent on
the disk IO.

By removing all disk destinations, things ran much faster.

I'll need to test a little more, but I would wait for my test before "debuging" this.
