hi. the performance of the run/job
https://ci.eclipse.org/xtext/job/xtext-core/job/master/416/console
is terribly slow.

could you lease check if there is something broken?

thanks
Christian

Which part is slow?  I need some numbers or tasks.

15:35:25  > Task :org.eclipse.xtext.tests:generateTestXtext
15:40:47  > Task :org.eclipse.xtext.tests:compileTestJava

vs on a good run

13:59:41  > Task :org.eclipse.xtext.tests:generateTestXtext
14:00:19  > Task :org.eclipse.xtext.tests:compileTestJava

similar performance drops through other parts of the gradle build

e.g. 

15:12:50  > Task :org.eclipse.xtext:compileJava

https://ci.eclipse.org/xtext/job/xtext-core/job/master/418/ took 25 minutes, which seems to be par for the course.

419 is now running on one of the fastest nodes we have.

Could simply have been a combination of lots of simultaneous builds + yours happened to run on the slowest node + that slowest node was really busy.

problem is there again:

https://ci.eclipse.org/xtext/job/xtext-core/job/release_2.22.0/3/console

any idea how to avoid this.
this makes it basically impossible to build a release milestone
without spending 20 hours

I'll duplicate this to bug 563645
