I'm building protobuf 3.1.0 for rawhide. The arm build is incredibly slow.
See http://koji.fedoraproject.org/koji/taskinfo?taskID=16512668
Entire x86_64 build took 21 minutes. Steps in the isValidUtf8Test look like:
Nov 18, 2016 4:18:01 PM com.google.protobuf.IsValidUtf8TestUtil testBytes INFO: Round tripped 18304 of 65536 Nov 18, 2016 4:18:01 PM com.google.protobuf.IsValidUtf8TestUtil testBytes INFO: Round tripped 18304 of 65536 Nov 18, 2016 4:18:02 PM com.google.protobuf.IsValidUtf8TestUtil testBytes
It's been running for over 11.5 hours on arm, and test steps look like:

and has increased in time to:

Have there been any other reports of issues like this on arm?
My understanding is that it is slow because there is no JIT for arm. Please correct me if I'm wrong. I ran Java on Debian on my Mac Powerbook (PPC) when the JIT wasn't working and it was unusable.

Yes, the 32 bit arm build of java-1.8.0-openjdk is using a Zero JVM. No JIT. So yes, it's slow. As an alternative you can try the java-1.8.0- openjdk-aarch32 package[1]. I'm not sure how stable that is, though.
Cheers, Severin

It is stable enough. And its main purpose is koji builder. In rawhide we are already providing java-devel in this package. So generally build root can get one from java-1.8.0-openjdk java-1.8.0-openjdk-aarch32 packages in random.
Maybe we can remove java-devel provides from java-1.8.0-openjdk on arm32 in rawhide ? J.

Yeah, that's what I ultimately decided as well. It does look like there is some progress upstream on this, so hopefully it will speed up at some point.
