Introducing a Pure LUA JVM luje
Monday, October 7, 2013
Right now it excels at anything which involves tight loops and float or doubles in local variables --- see the LocalBench benchmark. It'll comfortably beat Hotspot (on amd64, or Zero on ARM) with those. However, it does very badly with longs, as LuaJIT currently boxes those. Fields and methods of objects are stored in hash tables, so accessing fields in an inner loop will tend to cause luje to slow down. In any non-trivial benchmark it usually manages about 50% to 75% of Hotspot. Still, that's not bad given that the whole thing is less than 3000 lines of code.
