Some good news for package maintainers with many sub-packages:
Plague used to sleep at least 20 seconds for each (!) file it had to download from a builder. Even downloading the several small log files used to take at least 20 seconds *each*.
Reading and debugging the code, I found the source of the problem and taught the build server to sleep less when files are being downloaded. Interestingly, the speedup is noticeable even for tiny build-jobs, e.g.
revisor down from 7m to 4m nagios down from 6m to 4m
but it will be incredible for build-jobs with a larger number of pkgs (e.g. try moodle or nagios-plugins which are in EPEL already). That means, such packagers get the build-results and the mail notification much faster.
Michael, that's very cool. This has always been something that bugged me when using plague, but I never got around to figuring out why the "downloading" code was so slow, even locally. Would you mind posting a patch for plague with your changes?
The less aggressive [*] patch I've applied is this: http://mschwendt.fedorapeople.org/plague-0.4.4.1-faster-downloads.patch
With it, perl-Inline built in 1 minute while revisor built in 2 mins: http://buildsys.fedoraproject.org/build-status/job.psp?uid=37772 http://buildsys.fedoraproject.org/build-status/job.psp?uid=37771
