It seems that performance of Lua is improving steadily and Ravi
benefits from this as well.
Here are some recent test results.
Benchmark: matrix multiplication
Lua 5.3.4: 25.5 seconds
Lua (github): 18.3 seconds
ravi (computed goto): 16.6 seconds
ravi (computed goto & disabled lua hook): 15 seconds
ravi (computed goto & type annotations): 11.1 seconds
ravi (computed goto & type annotations and disabled lua hook): 10.6 seconds
luajit (v2.1 github, -j off): 9.4 seconds
All are interpreter timings on 64-bit Mac OSX 10.11.6.
I believe that LuaJIT's Interpreter VM has equivalent of computed goto
and disabled Lua hook by default - please correct me if I am mistaken.
I will share results from some other benchmarks - the trend is similar to above.
My impression is that on Mac OSX at least computed goto's are worth
having as an option.
