Neon-JDT Index poor performance [message #1739838]

i notice the index performance with Neon release is a lot poorer than the Mars.

The size of the index is taking at least 3-4 times size bigger than Mars. (by comparing the same projects and jars structure and compare the end result on the both release).

And Index speed in Neon takes a least 3-4 times longer too to complete the process.

Is this a known issue? is there anything I can help to improve it? Eclipse is used to deal with many big size jars in our company due to the NACA (cobol -to java compilation) usage. And the performance in NEON is totally killing it from using Neon. It just takes too long to do the indexing (comparing to previous release).

I'm not aware of any changes in Neon that could produce the degradation of indexing you describe.

From here I see two possible paths moving forward:

(1) You could file a bug against JDT/Core and provide data from a profiler that show which methods are consuming more time in Neon than they did in Mars. This path probably isn't easy: without access to a workspace that exhibits the problem we may need quite some quenstion&answer ping pong until we pinpoint the problem.

(2) The indexer is being rewritten for better performance as we speak [1]. The new implementation is scheduled to be shipped with Oxygen. That's a long wait, but you could soon start testing our integration builds (the new impl. is not yet in, but we're close), and provide valuable feedback before the release.
