--------------------------------------
Summary: Performance Regression in GroovyClassLoader.parseClass
After Migration to Groovy 4
Key: GROOVY-11726
URL: https://issues.apache.org/jira/browse/GROOVY-11726
Project: Groovy
Issue Type: Bug
Affects Versions: 4.0.24
Reporter: Puneet Singla
After upgrading to {*}Groovy 4{*}, we have observed a *significant increase in
compilation time* when using the following method from
{{{}GroovyClassLoader{}}}:
{{{{}}}}
{code:java}
public Class parseClass(final GroovyCodeSource codeSource, boolean
shouldCacheSource) throws CompilationFailedException{code}
{{{{}}}}
This function was previously performing optimally in Groovy 3.0.13, but with
Groovy 4.0.24, compilation latency has *increased significantly.* Earlier it
used to take about 4 minutes to compile a bunch of scripts but now it is taking
about 9 minutes for the same scripts.
----
*Steps to Reproduce:*
# {{Use {{GroovyClassLoader}} to compile Groovy scripts at runtime using the
{{parseClass(GroovyCodeSource, boolean)}} method.}}
# Use *GroovyClassLoader* to compile Groovy scripts at runtime using the
*parseClass(GroovyCodeSource, boolean)* method.
# Benchmark the time taken before and after the migration to Groovy 4.
