I have a large C project containing several thousand .c/h files. Everytime I modify a file, the code parser kicks in and takes a huge amount of CPU (even though I have dual-core CPU) hence makes the file editing very slow and unresponsive. This is a big pain in the ass. Although I can turn it off for project completely using project's context menu->Code Assistance->C/C++ Code Assistance, the problem is that when I turn off 'C/C++ Code Assistance', the code navigation stopped working completely. That's undesirable. What I think is really helpful is that we can turn off the DYNAMIC code indexing since every time you make some editing, the code indexer kicks in and slows down your whole editing, which is really painful. Adding this option to get around the indexer performance problem doesn't seem to be a very big task. I think NB should have on option where the user can choose whether NB should automatically update the index or update index immediately after every file-change. This feature is available in Eclipse IDE under C/C++->Indexer->Indexing strategy. If NB wants to gain support from developers of big projects, it should address this indexing performance issue as a high priority, because in big projects, developers need to navigate through a lot of files and make changes easily and quickly.
Now CND has strategy: keep code model in most accurate state. It results in performance issues. But CND can allow user improve performance by means of accuracy. So I can propose to tune following indexing options: ---------------------- Source Code Indexing Strategy Indexing of Modified File: - indexing on edit (default) - indexing on save Indexing of File dependencies: - index modified file - index all dependent files (default) Precompiled Headers: - rebuild precompiled header of file cache on file save - rebuild precompiled headers of all dependent files on file save (default) - switch off precompiled headers ---------------------- Is it clear? Is it approved by CND team?
I think this proposal makes sense. I would select 'index modified files' for most cases.
If we index only modified files and *never* index dependent ones, than sooner or later we'll come to a situation when code assistance works very bad. I believe that's rather a matter of *when* or *how often* should IDE reindex dependent files than whether to reindex them or not.
As workaround, you might try to turn off some highlightings in Tools->Options->C/C++->Semantic Highlighting. (Instead of turning off code assistance completely) Btw, could you, please, generate thread dump to see what's happened in your IDE? Thanks, Vladimir.

Could you, please, send us the information from View->IDE Log
How big is your project? Do you have enough memory? Could you try dev build? What if you turn off some of Tools->Options->C/C++->Semantic Highlighting?

My PC has Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz, 2G memory. My project has about 5000 C and header files. Turning off Tools->Options->C/C++->Semantic Highlighting didn't help.
>Heap memory usage: initial 32.0MB maximum 400.9MB Could you try to provide IDE more heap? For example: -J-Xmx800M of heap memory. Does additional memory solve problem?
I agree with wsonguci and alexvsimon. 'indexing on save' and 'index modified file' are very necessary options. Also I suggest to add "Reparse project" button in order to fix problems in code model.
here it thread dump. CPU is only loaded 50%. it is difficult to catch the exact moment of slowness because when you switch context between NB and console the picture can change 2009-07-24 11:22:56 Full thread dump Java

Hi, thanks for the dump. But I still see semantic highlighting tasks. Could you, please, turn it OFF and check responsiveness. In case of problems, please, provide the new dump. Thanks, Vladimir.
Added option "Reparse on Document Changed" in the "Tools->Options->C/C++->Highlighting" By default option is selected. If options is not selected the reparsing is not scheduled after each document changed event. Reparse will be only on document save or on invoking code completion. change set: http://hg.netbeans.org/cnd-main/rev/58f474b9552a
Integrated into 'main-golden', will be available in build *200910221401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/58f474b9552a User: Alexander Simon <alexvsimon@netbeans.org> Log: fixing IZ#168651 Add an option to stop the dynamic code indexing fixing IZ#152213 Large header files cause massive performance problem
