Well.... after reading all the comments I want to ask one thing... Why can't we be polite to each other? There are times when everyone has to ask some basic questions. Those of us who are "experts" now , did know nothing once. The spirit of a community is to welcome everyone and to help everyone getting started.

I have been hasitating in asking questions because i knew that i will recieve harsh and rude replies.

In my opinion, the biggest problem of dolphin is not the performance see more and scalability, but lack of community spirit and support.
