Luaj in interpreted mode performs well for the benchmarks, and even better when source-to-source (lua2java)
or bytecode-to-bytecode (luajc) compilers are used, and actually executes <em>faster</em> than
C-based lua in some cases.
or bytecode-to-bytecode (luajc) compilers are used,
and actually executes <em>faster</em> than C-based lua in some cases.
It is also faster than Java-lua implementations Jill, Kahlua, and Mochalua for all benchmarks tested.
