Description soldatov 2015-09-24 15:37:24 UTC 
I see this regression from March.

Prepare project
- Unpack clucene-core-0.9.21.tar.bz2
- Create project in automatic mode
- Set "C++ Standard" = C++11 in Project Properties window
- Close IDE

Check project
- Start IDE with fresh user directory
- Open project
- Call "Code Assistance|Test Error Highlighting" context menu item
==> Test stops in 'src/CLucene/config/gunichartables.h' files (I think IDE parses this file for a 90 minutes)

If I don't change C++ Standard field, then "Test Error Highlighting" test works quickly.
Comment 1 Vladimir Kvashin 2015-09-29 10:12:06 UTC 
Valera, is this a regression?
Does it work in previous IDE versions or with -J-Dapt.use.clank=false?
Comment 2 soldatov 2015-09-29 10:37:27 UTC 
1) -J-Dapt.use.clank=false doesn't fix test
2) last "good" test run is 2015-03-16

bash-4.1$ cat 150317_050938/..../testErrorHighlightingCluceneCpp11.main.log | grep gunichartables.h
Name = clucene_cpp11/src/CLucene/config/gunichartables.h, Errors = 0, Invalid identifiers = 0, Time = 1200.818, Lines = 11264

bash-4.1$ cat 150316_044142/..../testErrorHighlightingCluceneCpp11.main.log | grep gunichartables.h
Name = clucene_cpp11/src/CLucene/config/gunichartables.h, Errors = 0, Invalid identifiers = 0, Time = 16.747, Lines = 11264
Comment 3 Vladimir Kvashin 2015-09-29 11:46:58 UTC 
One more observation: we have the same problem with -J-Dapt.use.clank=false.
Comment 4 Vladimir Kvashin 2015-09-29 11:47:44 UTC 
(In reply to Vladimir Kvashin from comment #3)
Please disregard my previous comment, it concerned another issue.
Sorry.
Comment 5 Alexander Simon 2015-09-29 14:39:24 UTC 
regression after fixing bug #251181
Comment 6 Alexander Simon 2015-09-29 15:47:42 UTC 
I see two performance problem:
1. Method CsmOffsetResolver.findContext() puts in cache a lot of objects.
2. Method CompletionSupport.tryGetSeparatorFromModel() returns start of offsetable declaration instead of last separator offset.
