Zend studio slow performance

I am using Zend Studio 5.5 as a development tools to debug & complete my project.
Always found that the Zend Studio has slow performance issue while performing some debugging action. It always allocate a lots of Memory & CPU usage for its process (look picture below).


Previously, I did try to turn off the "Use OS Look & Feel" option inside the preference. It is increasing the performance. But today, I found that the slow performance issue is coming & I really cant take it anymore. So, I look for some forums & articles for the slow performance for Zend Studio.

Finally I found something is useful & try it out. Then I feel that it is faster than before although it is still slow performance at some time.

Below is the solution:

Sorry for the vauge necro-post here, but I've managed to find a solution to the problem.

1. Download the JRE v1.6 from sun: http://java.sun.com/javase/6/download.jsp
2. Install
3. Open the ZDE.lax file, located at: C:\Program Files\Zend\ZendStudioClient-5.1.0\bin
4. Locate: lax.nl.current.vm=..\\jre\\bin\\java.exe , and comment out this line with a preceding "#", or delete it.
5. Create a new line after the commented onecontaining the following: lax.nl.current.vm=C:\Program Files\Java\jre1.6.0\bin (assuming that is the path to the Java directory).
6. Save ZDE.lax and close it.
7. Launch ZDE.

Made a massive difference on mine; with no need to turn OS Look & Feel off.

Your guys if facing the same problem, may try this out!

P.s : I found that the Zend Studio 5.5 is best suit to JRE 1.5.0_12 version. The memory allocation only 150+mb.
