Hi Alex,
Sorry for the bulleted nature:
1. No error messages should indeed mean successful completion. Can you also
link me to apf_debug so I can add this to my own tests?
2. I went ahead and committed the capitalization fix, thanks!
3. Are you sure you are trying the non-optimized version correctly? I just
tried on a separate machine and I get nearly twice as slow results with
non-optimized language.js (on my macbook air):
optimized: 4644ms
non-optimized: 7327ms
The way I'm doing this is:
in language repo:
non-optimized
$ cd path/to/language/repo
$ git checkout master
$ cd path/to/language_speed_test
$ language -g path/to/JavaScript.language > JavaScript.js
$ node run.js ../jquery.js
optimized
$ cd path/to/language/repo
$ git checkout optimizations
$ cd path/to/language_speed_test
$ language -g path/to/JavaScript.language > JavaScript.js
$ node run.js ../jquery.js
I am also on node 0.4.1 but on Mac OS X 10.7
Thanks,
Francisco
