The only thing I see if from the official Github page : "This project is still under heavy development, but it's showing promise. In initial benchmarking with a hello world server, this is between 2 and 4 times faster than nodeJS."
Memory usage should be lower too.
Indeed. In that benchmark I did, it was 2 times faster on 32-bit linux and 4 times faster on 64-bit linux. In both the Luvit version used about 40x less ram. Also startup time is much faster in Luvit. This doesn't matter as much for servers, but for embedded devices like writing webOS games for the TouchPad, it makes all the difference in the world!
Node depending on how you build it can take between 300 and 1000 ms of time and 10Mb of ram to just start up on the TouchPad. Luvit starts instantly and uses much less ram.
Larger programs are needed to see how the memory usage and performance scales with real work. That could be completely different.
I have used Lua at the command line on machines with 64GB of RAM to do ad hoc data mining that would have otherwise required several days of prep time for writing and debugging C before each run.
Using Lua, I could do things in hours that used to take overnight, or several days.
