I always recommend (Maxthreads X 0.5) as the allocation factor, so 13 is correct. I
used 2 simply as an example of running out of bandwidth to allocate.

The only reason I don't recommend this setting is because I assume that you have a
server that does not have all threads busy at one given time. So, you may want to
allocate more bandwidth to the first threads. If you have a model where all threads
are busy then you would set the AF to 25.

I've always said that AF should normally be 1/2 of the thread count. You can, of
course, use a different model.
