I see similar performance levels when optimizing the Grails 7 test
application with `-Dgroovy.indy.optimize.threshold=0
-Dgroovy.indy.fallback.threshold=0` and `optimizationOptions.indy = false`. In
my testing Java 25 provides ~23% performance improvement over Java 17, but not
enough to resolve the 4x performance hit by itself. `optimizationOptions.indy
= false` was ~6.5x faster than without any optimization on Java 25
To help with further debugging I ran with `-Dgroovy.indy.logging=true
-Dgroovy.indy.debug=true` and without the other optimizations. Additionally I
updated `spring-logback.xml` to log to a file at Log level INFO. This
generates >500MB of logs during application startup and the initial loading of
data.
Here are two 100MB compressed logs and hopefully these can help. `call site
stays uncached` appears throughout both files.
