Question about the GitLab runners at cl.net

I have been having troubles with the ASDF tests on GitLab.  The ASDF test=
s are timing out reliably on Clozure Common Lisp after an hour.  The same=
 tests on a local Linux server takes only 2m30s.

This machine has 16	cores, but the ASDF tests are not multi-threaded.  Th=
e processors are Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz

Those are pretty good, but by no means cutting edge.

So I'm wondering if there's anything funny about the configuration of the=
 GitLab runner.

Thanks for any insight.

If I can, I will mirror this repo locally and see how the runtime differs=
 on our runner.
