Eric Milles updated GROOVY-11726:
---------------------------------
Description:
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.
# Benchmark the time taken before and after the migration to Groovy 4.
