I can give any comments only by looking at the profile (the output of the 
above command), and preferrrably the test data.

It's possible that V2 has some specific poorly-scalable code that decreases 
performance on your project. And if you use synthetic tests, it might be 
the case that it hits non-scalable parts that won't be hit by real projects.

So: give me more data.
