Description andreas1970 2008-11-21 00:49:01 UTC
Hi, I already complained about bad (ridiculously bad!) performance in NB 6.0, and the answer was: wait for the next
release, everything will be better! Now I switched to 6.5, and responsiveness is even worse. Opening a small PHP project
with only a few classes takes quite a while. Task scanning and later file indexing takes forever. The IDE GUI is not
responding for minutes, while java CPU load is at 100%.

I switched back to Eclipse, but thought give NB 6.5 a try, and now that!

Could you please provide thread dump while the problem is being encountered?

Reassigning to php for further evaluation.
Comment 2 Petr Pisl 2008-12-04 14:21:25 UTC
Hi Andreas1970,

could you provide more the time, how many seconds takes the task scanning and indexing? You can close the task scanning
window to stop task scanning. How many files is in your project?
Comment 3 andreas1970 2008-12-06 17:40:47 UTC

I work directly in a virtual host directory, which has several symlinks with thousands of files attached to it. Now, NB
scans all of those symlinked directories. The question would be, how to stop this scan task.

Somehow, this process is faster now; seems NB puts the results in some kind of cache or so?

Since there are some larger PHP projects like phMyAdmin in the vhost directory, it would be a good idea to be able to
exclude directories which should not be indexed. (Since task scanning for them takes long, as well.)

Comment 4 Petr Pisl 2008-12-08 15:43:18 UTC
Are you talking about indexing or about task scanning? If about task scanning, then just switch off the window or set up
the filters.

The full indexing is provided only at first time when a project is opened or created and the result are stored in a index.

Incomplete for a long time => will be closed
