Created attachment 158571 [details] Shows the issue - screenshot I have a project with many dependencies. When I call code completion on public class Foo{ public Set<IMasterData> allMDOs=new HashSet| //CC at | } then it takes 5s to present a tiny list of CC. I provide you a sampling snapshot and a screenshot, which shows that the time is spend in org.apache.lucene.search.BooleanScorer$BucketTable.
Created attachment 158572 [details] Selfsampler snapshot
Created attachment 158724 [details] Another sampling
The self-sampler shows that the time is spent inside Lucene index search; the second sample shows a lot of time is spent in WinNTFileSystem.list - which could indicate some FS slowness also affecting Lucene performance. Tomasi, could you advise ?
