Load testing on Qt - Server?

Question

Qt

Hello!
There is a client-server project, a messenger. All logic and interaction are registered, it is already possible to put the server on a separate machine and use it. Yes, I will clarify, the server has both multi-threaded functions and not, which work in one common thread.
And I wonder how to check the maximum load and by what means can this be done (roughly speaking) for a desktop application written in Qt?
jMeter, Ya.Tank - maybe look in this direction?
It seems to be easier for sites, I drove in the URL and watch the "attacks", and then ..

Launch many clients, let them exchange messages.
