You may already be aware of the issues but I tried out the latest build in our production environment and it crashed in a few minutes.
After about 2,000 people connected, no more socket connections could be established. (Usually we have about 12k users online without an issue)
Unfortunately being a production environment I couldn’t spend much time trying to find the cause and had to roll back.
I did notice the memory went crazy - ie filling up and cleaning far too fast - the java-monitor graphs are a mess.
I know you are working towards creating a release version so wanted to point out this issue incase you weren’t aware of it.
Has any performance testing been done on the latest versions?
Hope this is helpful.
