I believe the mirrors in the apache github org have a shared resource
pool at Travis, while jobs for your personal forks run in the global
resource pool. Its not unusual for the latter to be quicker off the
mark, but even then its usually just seconds of difference.
Occasionally there can be a backlog from having really large jobs or
many jobs from other projects but typically its not been an issue for
long. Using Appveyor as well can help too as they tend not to be
backlogged at the same time and the additional env is useful in
itself.
