lagging php file

rendering problem when navigating with keyboard and mouse (very very slow compared to netbeans 6.9.1)

To reproduce open the php file in attachement
press and hold the "down arrow" and notice the rendering lag.

I'm not sure if it is related to the php editor or all the editor...

let me know if i can help you to fix this problem !
Comment 3 Petr Pisl 2011-05-02 12:28:00 UTC
Is it reproducible always? I can not notice the slowdown. Could you provide a head dump at the moment?

Thanks.

Although I can not say that is very very slow, I have now feeling that is the scrolling really slower than in NB 6.9. Although the processor is 100% consumed and the memory is growing during scrolling.

After going through the two attached snapshots and talking with editor guys, I reassign the issue to the editor infrastructure.
Comment 6 Miloslav Metelka 2011-05-18 08:58:50 UTC
I have several performance improvements in the view hierarchy that I'm currently working on and that should be available in 7.0.1.
Comment 7 Simz 2011-05-18 13:50:15 UTC
is it possible to test it in a developper preview ?
Comment 8 Miloslav Metelka 2011-05-24 08:55:17 UTC
Yes, once I integrate the fix it will be first available in dev builds and then I will also integrate it to a branch for 7.0.1.
Downgrading to P2 since this does not qualify as P1.
Comment 9 Miloslav Metelka 2011-06-08 11:38:29 UTC
View hierarchy performance improvements will be integrated in terms of issue #197534.
