Re: GWT Compilation Out Of Memory

1. is there any relation between split points & *.cache.html files.
2. what should be the supposed ideal time of compilation for my application. as I have mentioned the size of war generated after compilation & keeping the system configuration in mind.

folders & files size generated in war files are as follows:
  1. deferredjs folder contains 5 folders (441mb of js files cumulative)  
  2. *.gwt.rpc 647 files (308mb cumulative)
  3. *.cache.html 5 files (27.9mb cumulative)
  4. *.nocache.js is 8kb
  5. and other folders

GWT version: 2.6.1

My Application is producing 1.6GB of war file and taking 7 to 8 hrs. for complete build of 5 permutation.
configuration of machine on which we are compiling is:
OS: windows server 2012 R2
Processor: Intel R ZEON R CPU E3-1225 V5
Core : 4

we have defined gwt compile parameters as follows:
GWT Compiler JVM Arguments: -Xmx61440M
GWT Dev Mode JVM Arguments: -Xmx61440M
GWT Test JVM Arguments: -Xmx61440M

we are facing two major problems:

  1. from last few days we are receiving out of memory error during compilation.
  2. it is taking very huge time to build.

we wish our project could break into smaller sections (modules compiled individually separately) and bundled in a single war at the time of release. like we use multiple dlls and use it in single exe. and in case of changes in any dll we need not to build whole exe again instead we only compile a dll and deploy it to client.

any suggestion \ help will be highly appreciated.

thank you!
