Jdt build process will reuse existed index files from my box, so that I assume jdt could use less time to parse jars to get indexs.
If can’t reduce time, does it mean it can’t contribute to eclipse performance?
But from guide, it claimed use existed indexes could improve performance…

The build process itself does not use any indexing information and so cannot contribute to
increased build times in and of itself. Not sure what else is at play.
