That's something proposed several times in the list.
In our installation, we used the default (4 threads) for a long
time -- until we met overload situations (all 4 threads in
use over long periods of time) when we switched to 6 threads.
However, in our situation not only Zope handles the application.
Beside that there are backend resources such as various databases
that can work concurrently with Zope. Therefore, our
application is not CPU bound (at least not on the host, Zope runs on)
and increasing the number of threads can increase throughput.

You have read my message to the end (and Florent's comment)?
If you have a single thread, then a single long running
request would exclude all other (maybe very short)
requests until it finisches.
I am convinced that you want some degree of concurrency
to favour short running requests. 4 threads is not too a
