An interesting tweak posted at "Andrew Pollack's Blog" long back on "Making Notes 8.x (including 8.5 beta) in Eclipse feel much faster" Thanks to (AndrewP)
Increasing the vmarg.Xmx= value on "jvm.properties" actually improves the performnace. Details are available on Andrew Polloack`s Blog.
I made this change on my 3GB Laptop , bumped the setting to 1024 and i see some improvements.
