[jira] [Commented] (GROOVY-9588) groovyCompile 6x slower in 3.0.4 than 2.5.6

["Eric Helgeson (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-9588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17150306#comment-17150306 ] 

Eric Helgeson commented on GROOVY-9588:
---------------------------------------

It is much faster with a high threshold. 6 minutes vs 30+. Though the compile did us 10g of heap.

Do you think the default of 64 is a bit low? I would think that would be hit by every project except the smallest.

> We are upgrading a large Grails app with 400+ controllers, 550+ services, 350 domains, 4000 files with 950k loc to Grails 4.1.0.M1 + Gradle 5.6.4.
> Using Gradle 5.6.4 with Java 8 & Grails 4.0.3(Groovy 2.5) a clean/groovyCompile took approximately 5 minutes.

> Using Gradle 5.6.4 with Java 11 & Grails 4.1.0.M1(Groovy 3.0.4) a {{clean}}/{{groovyCompile}} takes 33 minutes on a 2019 MBP w/ 2.4 GHz 8-Core Intel Core i9 & 64gb of RAM.
> I have tried giving the groovyCompile task 16/32gb of ram, with no noticeable change. I've also tried -Dgroovy.antlr4=false - but this gave other compile time errors I did not see with it set to true (so was unable to have a full successful compile)
