Hi!

See my another comment. Transaction is a very complex functionality, so there is a big probability that such slow down is because a lot of debugging code - more complex code -> more debugging code in beta -> more slow down.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
