Hello All,
After the other day having switched over to Gradle 1.6 from Gradle 1.5 I have noticed a significant performance decrease in the initial configuration step in Gradle 1.6 compared to the 1.5 version. With initial invocation of gradle I mean after having done a clean code checkout invoking Gradle for the very first time.
See numbers below. Are you aware of any performance issue associated with the 1.6 version?
I have not adjusted my build script for changes pending (for Gradle 2.0) so I do see some new deprication messages.
My Gradle project is fairly large I’d imagine. It is a multiproject containing 198 subprojects.
Performance numbers for an initial ‘gradle tasks’
Gradle 1.6:
===========
Total time: 5 mins 25.951 secs
Total time: 5 mins 47.84 secs
Total time: 5 mins 32.74 secs
Total time: 5 mins 7.843 secs (no daemon)
Total time: 5 mins 31.888 secs (no daemon, profile)

Across the board the configuration time per subproject is about twice that of Gradle 1.5. The other items are virtually identical. I also supplied the dependency resolution times.
Subsequent invocations of ‘gradle tasks’ are done in ~35s for both Gradle 1.5 and 1.6.
I hope this aids you in your analysis.
Thank you, Stefan Marklund
