Tested performance of polymorphic calls (I skipped previous version): dart is beating java hands down now. by 30% in "extends" and by 40%+ in "implements".
(compared with "client" java).
There are about 20 other benchmarks where we are not there yet. But getting closer.  :-)

[Alex Tatumizer]

Also, beating java in String.fromCharCodes (in case of ASCII) - by as much as 5% !!!
Though, we are still very far behind in int.toString() (don't want even to mention by how much).

Where can I find these benchmarks ?

Thanks for the editor.
Can we please get:
- Tab characters
- automatic source code formatting

I am waiting for that since the beginning.

Just copy file and run. Don't forget to turn off checked mode :-)

I was planning much broader set, with parallel java stuff, but delayed it until overall results improve. Right now, my java tests are very limited, I didn't even put them on github. If there's interest, I will do more.

All the measurements are done per "unit" (byte, 16-bits, code unit, int etc). This provides common denominator for all tests (otherwise they won't be comparable with each other).

Is it just me or has 'Ctrl + /' Toggle Comment stopped working? 

Cheers,

Davy

[Alan Humphrey]

"Ctrl + /" Works for me on Ubuntu.

[Davy Mitchell]

Working on my Lubuntu machine now - will retest on my Windows machine tomorrow. Very strange! 

Thanks,

Davy

It's currently broken on Windows.

[Alex Tatumizer]

Strange. CTRL-/ (Comment/uncomment block) works for me on both Win Xp and Win 7.

[Jos Hirth]

Hm. You're right. It works with r22879 for me (Win8 64), too.

I hadn't tried it, because it usually didn't work whenever I tried it. It's also kinda inconvenient to use with a German keyboard layout (Ctrl + Shift + 7).

Working for me now on Windows!
