So, If you can change this java heap size, then you will be able to improve the performance.
click below links for information's about java heap size.
Following are steps for increasing and managing manually the heap size.
Go to the eclipse folder where you extract the eclipse zip file. Note the path to eclipse.exe file as shown in figure below.
Now you can add code segment for manually managing heap like below.
D:\eclipse\eclipse.exe -vmargs -Xms1024m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=1024m
you can change above size as you wish, for example
D:\eclipse\eclipse.exe -vmargs -Xms512m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m
Now, open the command prompt (click start then type cmd and press Enter).
Copy the above code (D:\eclipse\eclipse.exe -vmargs -Xms1024m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=1024m).
Then, right click on cmd and press Enter. It will open the Eclipse........
You can also make a shortcut with these setting to future use without doing this every time when you start Eclipse.
For making shortcut, go to the eclipse extracted folder and right click on Eclipse.exe and click on Create a shortcut. It will create shortcut of eclipse, now right click on that short cut and select properties like below figure.
Hence, add above code (D:\eclipse\eclipse.exe -vmargs -Xms1024m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=1024m) to target filed of that and click OK button.
Now, you can use this shortcut for starting Eclipse with these setting easily.....
