So this finally has happened ;) Check out this post in ORMBattle.NET Forums.
Igor, my congratulations ;)
I'll re-publish this in ORMBattle.NET blog in ~ 1-2 days, and update the scorecard ~ in 1 week (on its next update). Delay is related to necessity to implement at least one tweak added by Igor to all the other tests (it must make all the results a bit better on small sequences), as well as the lack of time. I already spend a lot of it on preparing the current scorecard, but by some reason has finally lauched BLToolkit tests, that were committed just today in the morning :)
