I'm currently using MYSQL,

and it becomes the bottle neck of the whole system

+2  A: 

Try Lucene indexing: lucene.apache.org. There is also a very good implementation in PHP as a part of Zend Framework.

How much out performant is it compared with nutch?I've used nutch,and it sometimes is not that fast neither.

Lucene-based systems need a lot of tuning to become performant. If you get it right, though, they're extremely quick.

I've read much reference about nutch,but rarely on tuning,could you give a link?

A: 

Consider Solr (not to be confused with the Solar Framework for PHP). It is based on Lucene and designed to scale, if that is one of your concerns.
