Description oro CLA 2003-01-18 15:06:21 EST 
I would like to see the performance of the SearchEngine improve and possible the
time need to build a AST from a java file to be reduced.

I think "code assist" and "auto correct" features depends on those 2 things. If
the performance of the SearchEngine improves, the "code assist" response time
can be improve. Right now, there is a short pause in "code assist". 

And if the search engine can be improved , it can help out other JDT plugins
(e.g. the plugins for calculating metrics)

CodeAssist doesn't use the DOM AST, neither does the SearchEngine.
They use the compiler internal ASTs.

Please provide suggestions for improvement.

What performance numbers are you getting ? Steps to reproduce ? Build number ? 
Machine type ? RAM ? Which JRE are you using ?
