How to improve Netbeans performance?

Question

Is there a real way to get Netbeans to load and work faster?

It is too slow and gets worse when you have been coding for some time. It eats all my RAM.

Answer 1

A more or less detailed description, why NetBeans if slow so often can be found in the article:

Boost your NetBeans performance

First. check what NetBeans is actually doing on your disk. On a Mac you can issue this command:

  sudo fs_usage | grep /path/to/workspace

In my special case I got a directory which didn't exist any longer, but NetBeans tries to access the folder all the time:

  14:08:05 getattrlist /path/to/workspaces/pii 0.000011 java

Repeated many, many, many times. If you have a similar problem, fix it by deleting your NetBeans cache folder here:

   ~/.netbeans/6.8/var/cache

If your NetBeans.app is still making a lot of disk I/O. Check if it's accessing the subverison folders and svncache.

I had to disable the subversion features with config file:

  ~/.netbeans/VERSION/config/Preferences/org/netbeans/modules/versioning.properties 

add a line:

  unversionedFolders=FULL_PATH_TO_PROJECT_FOLDER  

SOURCE: Netbeans forums

IMHO it's mainly related to a lot of disk I/O caused by missing files or folders and svncache.
