GWT SuperDevMode slow

more options


I work on a software development team and have a large(ish) Google Web Toolkit (GWT) application (~1M LoC client-side).

We're able to launch the webapp (with different mechanisms; command-line, IDE's etc) and debug with GWT's Source Maps on Google Chrome; however FireFox (tried different versions from 40.0 up to 50.0) is painfully slow - to the point of incredibly slow and unusable (I know "times" are relevant to hardware etc, but in the order of >10mins for Debugger Tab to even load). Invariable the connection between application server and browser is reset before FF completes.

Everything is running on localhost; so no network concerns.

Any help would be much appreciated.

If I disable "Show original sources" the Debugger Tab loads quickly; however - obviously I have no Source Mapping in operation. Enabling "Show original sources" pauses the browser for ~6 minutes whilst Source Maps are presumably processed. This is marginally better than having "Show original sources" when the application first loads. Actual use of "Debugger" remains untenable.
