Hi Nick,
The unit tests on Nadron do some micro load testing. The following
client has sessions numbered at 50, however you are free to increase that number/spin up more processes to do a load test.
The development of nadron is limited to fixing bugs, moving up some library versions and such, since I have been a bit busy. Obviously it would not have the same level of support of a commercial tool like smartfox. In my experience people use nadron in two ways, 1 as it is and building on top of it and 2, they use it as a reference architecture to build out their own with mostly the same libraries(netty etc).
Thanks,
Abraham.
