Using a fixed number like that does not make sense, it's actually a
function of
how many cores you have, and what type of traffic you're driving.
E.g., for WMS I'd put it at 2-4 times the cpu cores, but for WFS it can
go further, and for GWC much further.
Suggestion: use control-flow instead, and leave the tomcat number to
some suitably high value (200 is a good starting point with lots of GWC
traffic it might be higher)

See above. Try to do load GWC with jmeter with increasing
number of connections and see where the thoughput tops.
That's your number for GWC

Sounds like a good plan.
