We're merging two physical servers into one (newer) server with better hardware. Response times with the website and general game connectivity should be noticeable. We're also switching our backend website code from Python 2 to Python 3 to stay current and receive the performance benefits that 3 has to offer.
Also, as a tease... The improvements with this are also opening up the ability for us to create a public test server (apart from the main production server). More on that coming hopefully soon.
FPS is a client-side (not server-side) issue. Our Pypperoni project - a rewrite of the game client's backend compilation - is aimed to help with this. Pypperoni is a compiler that takes the game's code, written in Python, and converts it to the C programming language. Pypperoni will also feature a much newer version of Panda3D, the game's graphics engine, which we've worked to heavily optimize. The newer Panda version will also fix a lot of current client instability in settings where a lot of players are present. Pypperoni is coming at a later date, so stay tuned.
