[MacRuby-devel] Speed

[Uliano Guerrini]

Thank you all

I didn't realize that JIT in macruby is compiling on the fly the code piece a piece (I thought that a source file was the compilation unit) and so JIT time to compile the block was inside my time metrics

I re-run the test looping many times and the results are speaking for themselfs:

uliano$ macruby fib.rb 
sum of even Fibonacci less than 4000000 = 4613732
time = 0.637182
uliano$ /usr/bin/ruby fib.rb 
sum of even Fibonacci less than 4000000 = 4613732
time = 4.710929
uliano$ ruby fib.rb                               # this is Ruby 1.9.1 from macports
sum of even Fibonacci less than 4000000 = 4613732
time = 0.660384
uliano$ macrubyc -o fib fib.rb
uliano$ ./fib
sum of even Fibonacci less than 4000000 = 4613732
time = 0.61873
