Thanks for the response.
1. Replicated the problem on Linux with Java 1.8.0_45. It goes away if I
run the script as follows:
JAVA_OPTS=-Xverify:none groovy IteratorBug.groovy
2. I can demonstrate: Checkout https://github.com/wcraigtrader/ogp, run
with Java 1.7.0, twice, as follows:
./gradlew run -GV=1.8.9
./gradlew run -GV=2.4.3
Compare the times -- Groovy 1.8.9 is faster for this simulation of my
application (and even more so for the actual application).
I just tried this out... since I don't know what to look at I give here
my final results
./gradlew -PGV=1.8.9 run
|-- elapsed time [Initialize data] 0,214 seconds.
|-- elapsed time [Create database] 2,166 seconds.
|-- elapsed time [Ingest data] 97,031 seconds.
|-- elapsed time [Database cleanup] 0,028 seconds.
|-- Total [GraphPerformance] 99,447 seconds.
./gradlew -PGV=2.4.3 run
|-- elapsed time [Initialize data] 0,298 seconds.
|-- elapsed time [Create database] 2,358 seconds.
|-- elapsed time [Ingest data] 95,840 seconds.
|-- elapsed time [Database cleanup] 0,032 seconds.
|-- Total [GraphPerformance] 98,555 seconds.
./gradlew -PGV=2.4.3:indy run
|-- elapsed time [Initialize data] 0,378 seconds.
|-- elapsed time [Create database] 2,196 seconds.
|-- elapsed time [Ingest data] 174,907 seconds.
|-- elapsed time [Database cleanup] 0,025 seconds.
|-- Total [GraphPerformance] 177,518 seconds.
So for me the indy version is significantly slower, while the primopts
versions are very similar in performance, with 2.4.3 being maybe faster,
but that may very well be within the variation
