Eclipse PDT is freezing from time to time

I am usign Eclipse PDT Helios and it sometimes freezes for 2-3 seconds even when working with small PHP files, like 10 rows without any includes in them or any complex statement that may cause a problem while parsing. My machine has more than 3GB RAM and I have setup the HEAP size to 990MB. The CPU is Intel E7500 2.9Ghz.

What could be the problem? It is annoying to work like that. I understand when it "thinks" for few seconds when opening large files like > 50KB but how about the small ones. It also freezes when I am making a change or I save the file. This is slowing the development process. I can have a freeze every min or 2 :(

Not sure if this is the right forum, but this is a programming problem connected with the IDE so I guess people here will not mind helping me if they can.

I am using Eclipse for PH开发者_高级运维P development with Subclipse installed and my working copies are on a server in our local network.

My current eclipse.ini is

-startup

plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810

-product

I wrote an article on speeding up PDT indexing. It might help.

There are known issues with PDT 3.1 and eclipse 4.2 (juno).

This is the solution:

Open a different perspective (for example java, but not php) and restart eclipse. Afterwards you can savely switch back to php perspective. Eclipse will have no (pdt induced) performance issues.
