I have a GWT (we are using version 1.5.3) based application having a
large number of forms/screens. It has a single EntryPoint. Application
has become very slow as it takes lot of memory. Now we are running
into memory leak problem, my application sometimes takes huge amount
of memory (more that 200MB) if it is run for a long time in a single
browser. IE is the official browser.

I have done some investigation and came up with these points:

1. Huge Application is using single EntryPoint (only one module).
2. Application have a large number of Sigleton objects. Even the Main
Panel which is attached to Root Panel is singleton.

Can someone suggest these Singleton objects cause Memory Leak. Or may
there some other reasons for it.

Also suggest me what corrective measures I can take to reduce this
problem.


Thanks in advance for your help!
