Hi Thomas.

I'm using Ubuntu 12.04 64bit with a Gnome-shell 3.4.1 on Inspiron 1525 (Core(TM)2 Duo CPU T8100, 4Gb RAM, Agility3 128Gb) as a developer notebook attached to a FullHD monitor.

So, i'm using standart display 1280x800 + 1920x1080 and have no significant performance issues (GTK LaF).

Looking at the issue from your letter, the problem caused by bad implementation of nvidia drivers and compiz problems.

First part can be probably solved by newly released nvidia drivers (significant performace improvements up to 50% in some cases). Compiz problems can be avoided by not using default Unity desktop (gnome3 aka gnome-shell is one of many other options) :)

Hi,

I tried to investigate why Netbeans was feeling so much slower compared
to "other non swt ide".
Especially I could not believe that simple stuff like "opening menu
item" or "minimize, then restore" should take 1 second or so.

If you look into issue
http://netbeans.org/bugzilla/show_bug.cgi?id=221862
you can see that Petr Cythelsky pointed me in an interesting direction:
GTK drawing seemed to put the brake on Netbeans.
Indeed: When adding "--laf
com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel" Netbeans is *much*
faster, at least a factor of 3-4 on my machine!

Speaking about my machine: 2 Screens with 2560x1600 each, Nvidia
graphics card, 6 cores AMD running latest Ubuntu 12.10.

I wonder if
a) somebody is able to reproduce my findings
b) there is any way to increase the GTK performance (is it a JVM issue?
Can we/Netbeans/Oracle put some mild pressure there to get that fixed?)

I always hated to be in an IDE shootout with Netbeans loosing on the
performance side.
Now I realize this does not have to be the case, let's get that fixed!

Regards,
Thomas

PS: In case somebody wonders, Linux is used by developers and enterprise
customers. F.e. in my city there is an insurance company having >500
developers/IT users running Ubuntu with several thousand end user work
stations running Linux/Java-Swing.
