Are you feeling your
eclipse is slow ? And, is it taking lot of time to open your eclipse ?
Based upon my experience I have put down some points that
would help you out.
1. Try
to open your eclipse in clean mode.
Command: > eclipse –clean
What is does ?
Cached data used by the OSGi framework and eclipse runtime
will be wiped clean. This will clean the caches used to store bundle dependency
resolution and eclipse extension registry data. Using this option will force
eclipse to reinitialize these caches.

2. Configuring
suitable heap memory size in eclipse.ini file. Verify max heap size parameter (Xmx)
and configure based on the application need.
Example: -Xmx1024M
This is where your java
objects will be stored.
3. Make
sure to configure sufficient permgen size in eclipse.ini file. Configure based
on the your application need.
Example: -
-XX:PermSize=256m
-XX:MaxPermSize=512m
This is where you classes and method definitions will be
loaded after starting your application
4. Close
unnecessary projects in your workspace.
Example: You might have 10
plug-ins in your eclipse current workspace, but you might be using or working
on only 2 plug-ins, and that work independent of other plug-ins.
5. Try
to avoid force closing eclipse. It takes
lot of time to initialize the previous state of eclipse based on the history indexes.
6. Don't
enable all third-party code enforcement tools by default.
Example:
- Find bugs - run based upon need.
- Google code analytics
- Check style
7. You
can remove Project build automatically option in eclipse and enable only based
on the need.
8. Remove automatic
updates for eclipse plug-ins and third party plug-ins.
You can find “Automatically
find new updates and notify me” option in your eclipse.
8. Once
in a while try to switch all your plug-ins/projects in to new workspace and
work.
As a programmer:
- Don't keep so much of code in your Activator start() methods
- Minimize the number of classes in the each plug-in
- Don't run too many background processes in your application.
- Don't create too many threads at a time. Make sure no.of
threads should be less than or equal to number of processor cores in the
system.
