I'm not sure yet. Honestly, it seems the Linux version is quite buggy and unstable right now.
The plan can change, but it's very likely we will need to get a separate server dedicated to NS2. Running it on our VDS isn't working out, tick rate is just all over the place, and I'd like to keep 20 slots.
I know things change pretty slowly, so just need to be a bit patient
If by then, it is shown performance on Linux is better then we would most likely switch if possible. One drawback to getting a separate server is we would need to change IP. We will have to make sure our regulars know about it.
