The numbers are matching our experience.

Y, indeed to get more CAPS , its about the same with 200 - 1000 clients

It is also matching our experiments.

If you see idle CPU remaning at your loading machine, you can try adding
more servers. Else, you can scale either by increasing the CPUs/memory
of the client and server machines or by increasing their numbers.
