Netbeans (and other Java apps) runs slow on Linux

I would like to create Java applications, but my first “brake” is that it is impossible to run Netbeans at a decent speed under Ubuntu 9.10 with a Radeon X1300 Pro graphics card, P4 3.2GHz.

If I use other software, like Monodevelop or any other non-Java app, I don’t have this run-slow problem.

This could perhaps be my Radeon card with my high resolution (1600x1050), so would I be better off if I bought another video card? Or is it a problem with Linux, the Java Virtual Machine or something else?

Are there any settings I should try changing in the netbeans.conf file? Would setting opengl=true or any other settings improve my Netbeans experience?

If you can run Netbeans without problems, what PC configuration do you have?

I know this is not strictly a programming question, but it is about developer tools and configuration.

I have personally noticed Netbeans slowness on Fedora 14 under a couple conditions:

  1. Using OpenJDK seems to be slower than Sun Java
  2. Using the radeon open source video driver

I've been meaning to install fglrx on my laptop to confirm this hypothesis about #2. See this thread for more.

  • Your CPU speed is fine.

  • Your video card is powerful enough. Video driver issues are possible, but not terribly likely.

  • NetBeans is RAM-hungry, there's just no way around it:

    • Make sure you have enough free physical RAM on your machine when running NetBeans. Ask Google for information about how to inspect and watch memory usage for your OS.

    • Maybe try closing one or two other RAM-hungry apps, if you have them running.

    • Try using the Sun JDK/JRE, it is more heavily optimized than other offerings.

I've run Netbeans on Ubuntu 9.10 and a Radeon card with no problems. One thing you may want to do is increase the memory size that the JVM allocates to Netbeans. this Netbeans wiki article should help you figure out how to configure it.

i think you should check your java virtual machine, i have used netbeans on various machines for java development and got no problems up to now.
