Would you guys mind if I distribute MCServer + LuaJIT binaries?

[DiamondToaster]

I'd like to make a repo for these binaries as, at least to my knowledge, they don't exist. I've sucessfully built binaries for ARM/x64 Linux that use LuaJIT instead of regular Lua without much effort. I saw a HUGE difference in speed and hoped it would help RPi2/Beaglebone users out here as well. It managed to broadcast 100000 chat messages to all clients in under 2 seconds while regular interpreted Lua took about 4 minutes.

WOW! This is just awesome!

Here, have an unprofessional Dropbox repo: (Hopefully temporary...)

Might there be way to compile this into the project and ship it within the MCServer binary? ATM I have to install luajit.

Hmm, that's odd. Especially since I used a static library. I'll look into it. Seems like it works perfectly with distro-packaged line though.

The process was extremely hacky, I was modifying CMake and link.txt files for this to work so I wouldn't doubt it if I did something weird.

EDIT: Sorry about that, I forgot to explicitly append .a in a link.txt file. I got a couple of static builds now. Unfortunately I can only target x64 and armhf now for some reason.

I was wondering if the speed increase from LuaJIT was anything noticable in the "regular use cases" - not something as synthetic as sending 10k messages, but normal gameplay. I don't think it's a bottleneck, but if it becomes something worthwhile, we might want to look at integrating LuaJIT in the base repo.

Good point. It might also be worth checking if a Lua world generator is faster in LuaJIT. As far as I know the only Lua generator we currently have is my FloatingIsland plugin.

I did notice a bit of a difference with my Beaglebone Black, a less capable device compared to the RPi2. It especially helped to decrease input lag on hooks such as left/right-click on my custom gamemode plugins. Now people at least have the option to do this, it compiled pretty seemlessly after some editing.

Can you post the changes needed. We might be able to make a less hacky version.

It would be awesome having this in the main repo! Many of my friends tell me that bigger plugins aren't that fast on MCServer and a big German Minecraft community is most likely going to switch to MCServer soon.
