Apart from the machine that I've described on the previous post, I do have another machine, its an AMD Phenom II X4 925, 2.79 GHZ with 4GB or RAM running XP Professional SP 3. Eclipse run really (I mean, really) slow in this machine.
The most annoying problem ever was that when i start hitting "." after a variable name eclipse will go into this retardation freeze for approximately 5 seconds.
The Important Bits:
1. Make sure that you're running the newest eclipse and SUN JDK.
2. Tweak your eclipse .ini file. Here's my current eclipse. ini file :
-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
org.eclipse.epp.package.java.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
384m
--launcher.XXPermSize
128m
--launcher.XXCompileTreshold
5
--launcher.XXMaxGCPauseMillis
10
--launcher.XXMaxHeapFreeRatio
70
--launcher.XX+UnlockExperimentalVMOptions
--launcher.XX+CMSIncrementalPacing
--launcher.XX+UseG1GC
--launcher.XX+UseFastAccessorMethods
--launcher.defaultAction
openFile
-Xms512m
-Xmx1024m
-Xss4m
The part that you might want to do differently :
-Xms sets the initial Java heap size
-Xmx sets the maximum Java heap size
-launcher.XXMaxPermSize allows for the JVM to be able to grow the PermSize to the amount specified. Initially when the IDE is loaded, the MaxPermSize will still be the default value but will not actually take up that amount until it is needed.
-launcher.XXPermSize controls the size allocated to compiled classes and permanent data structure.
-launcher.XXMaxGCPauseMillis=10 is *request* for the JVM to pause at most 10 ms.
3. Disable label decorations (Windows -> Preferences; General -> Appearance -> Label Decorations).
I only have Android Decorator, Java Type Indicator and Task Change Set Decorator enabled.4. Disable startup/shutdown task on startup (Windows -> Preferences; General -> Startup and Shutdown).
I disabled Usage Data Gathering/Recording.5. Disable spell check (Windows->Preferences;General->Editors->Text Editors->Spelling).
I'm coding, not writing a book.6. Disable auto building (Windows->Preferences;General->Workspace).
So...its mildly less retarded now...but I want a faster autocomplete...you know...like what Visual Studio has...
1. Go to Window / Preferences / Java / Editor / Content Assist / Auto-Activation and decrease Auto activation delay from 200 to zero
2. Patch eclipse

Replace <ECLIPSE_HOME>/plugins/org.eclipse.jdt.core_3.6.1.v_A68_R36x.jar with the file downloaded from the folder
