cookietwiikuuDo not try to run your server using the 64 bits binary, it is unnecessary.Would it not improve performance technically speaking? (assuming all the plugins work as intended)
The game server can only run the simulation on a single CPU core (skill issue).
In the current cases where resources are adequately provisioned (one CPU core per game server minus one overall for the OS/other tasks, and the CPU clock is fast enough to keep up with the simulation), the performance change won't really matter much.
It maybe gives a few more opportunities to run the server on slower CPUs, or if you wanna put too many gameservers up (don't do that, that's degenerate).
