LuaJIT: New Garbage Collector (2012)

Re:LuaJIT: New Garbage Collector (2012) by omginternets on Saturday December 03, 2016 @05:01PM (#13097718)

Is there something about lua that makes it amenable to the performance of luaJIT? In priciple, would it be possible to get comparable performance out of something like pypy?

In other words: is getting pypy to perform like luajit "just" a matter of time/money/expertise, or are there technical considerations?

Well, nothing really. It's just a matter of engineering, i.e. man-years put into the VM and the compiler.

That quote was in context of

What in your opinion keeps LuaJITs performance away from C/C++, i.e. what other "hard" things need to be solved?

TBH that was the spirit of my question. I was wondering if there was something special about Lua (the language), and it seems like the answer is a resounding "no".

So basically, I should donate to pypy...

I'm not sure I could call that "resounding" - for one a PyPy dev disagreed with him in a sibling thread.
