[ BUILD # : c0c8da2a52b0 ] [ JDK VERSION : 1.6.* ] To reproduce it, just press Shift in the beginning of large file (1500 lines) and them keep pressed the down key and you will see the IDE hands for several brief intervals. It is an awkward regression and make the editor terrible to work.
*** Bug 183400 has been marked as a duplicate of this bug. ***
see snapshot in issue #183400. 240 secs to select lines is "no-go" from C++ component. It's rather common to have big files in C/C++ projects.
The problem be demonstrated when doing cursor down/up in JTable. I have likely found the problem in HighlightsViewFactory and I'm preparing a fix.

Apologies, my original fix needed an improvement: http://hg.netbeans.org/jet-main/rev/90581ca5ee1a
One more rectification, please make sure that you have a build with all the changesets when testing. http://hg.netbeans.org/jet-main/rev/52bb703cd4a0
Integrated into 'main-golden', will be available in build *201004090201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main/rev/f94732b3cdae User: Miloslav Metelka <mmetelka@netbeans.org> Log: #182900 - The performance for select several lines is terrible.
Really fixed? I got the following slowness-detection at build 201004160201. --- It has now been added to the exception database with id #372090. It has been classified as a duplicate of report #167160. This bug was already fixed. Please update your build of NetBeans to the latest build of 6.9 where bug #182900 is fixed. If you are already using newer build and your report meets certain criteria new bug will be filled automatically. Your previous reports Thanks again for your help. ---

And it's working fine in a 5k lines file.
Performance while selecting lines is not so bad but the usage of CPU is much higher. (60-75%) The same behavior can be encountered for 6.8 either. Java: 1.6.0_18; Java HotSpot(TM) Client VM 16.0-b13 System: Linux version 2.6.31-20-generic running on i386; UTF-8; en_US (nb)
Downgrading the priority. Not a stopper for 6.9 beta.
I have just tried today's build on 20k lines file and selecting big parts of the file looked reasonably fast on my macosx. Sooo - is this problem still present in the current trunk?
David, I tested it a little bit with my local build I've just updated. I tested it agains an .sql file with 7857 lines and I get a slowness report [1] against another issue so I am not sure if both are related or not. What I did was: 1.Go to the last line of the file; 2.Press Ctrl + Shift + Home 3.With Shift pressed, I moved the caret for between lines up-to-down using the down key. After moving between some lines the slowness detector was activated some times, but was possible to work. BTW for java files, the experience was terrible with a 2560 lines file. I just can't work on it even without slowness detector showing me anything the editor responsiveness was at least terrible. If you need any additional detail just let me know.

After issue #183646 was implemented the selection should work fast (checked it on a file with 40000 lines). There was one minor problem though that I've just fixed. http://hg.netbeans.org/jet-main/rev/3032e330d928
