> Groovy 4 runtime performance on average 2.4x slower than Groovy 3
> -----------------------------------------------------------------
>
> Key: GROOVY-10307
> URL: https://issues.apache.org/jira/browse/GROOVY-10307
> Project: Groovy
> Issue Type: Bug
> Components: bytecode, performance
> Affects Versions: 4.0.0-beta-1, 3.0.9
> Environment: OpenJDK Runtime Environment AdoptOpenJDK-11.0.11+9
> (build 11.0.11+9)
> OpenJDK 64-Bit Server VM AdoptOpenJDK-11.0.11+9 (build 11.0.11+9, mixed mode)
> WIN10 (tests) / REL 8 (web application)
> IntelliJ 2021.2
> Reporter: mgroovy
> Priority: Major

> Groovy 4.0.0-beta-1 runtime performance in our framework is on average 2 to 3
> times slower compared to using Groovy 3.0.9 (regular i.e. non-INDY)
> * Our complete framework and application code is completely written in
> Groovy, spread over multiple IntelliJ modules
> ** mixed @CompileDynamic/@TypeChecked and @CompileStatic
> ** No Java classes left in project, i.e. no cross compilation occurs
> * We build using IntelliJ 2021.2 Groovy build process, then run / deploy the
> compiled class files
> ** We do _not_ use a Groovy based DSL, nor do we execute Groovy scripts
> during execution
> * Performance degradation when using Groovy 4.0.0-beta-1 instead of Groovy
> 3.0.9 (non-INDY):
> ** The performance of the largest of our web applications has dropped 3x
> (startup) / 2x (table refresh) respectively
> *** Stack: Tomcat/Vaadin/Ebean plus framework generated SQL
> ** Our test suite runs about 2.4 times as long as before (120 min when using
> G4, compared to about 50 min with G3)
> *** JUnit 5
> *** test suite also contains no scripts / dynamic code execution
> *** Individual test performance varies: A small number of tests runs faster,
> but the majority is slower, with some extreme cases taking nearly 10x as long
> to finish
> * Using Groovy 3.0.9 INDY displays nearly identical performance degradation,
> so it seems that the use of invoke dynamic is somehow at fault
