While initial implementation of dist-git style tasks support for taskotron-trigger and buildbot was sent for review (D808, D809), there are already couple of ways to make it more efficient since the implementation is more of "let's try it quickly if it works":

• try to git pull the task repo in trigger instead of git clone each time (we do shallow copy, so investigate if that's reasonably possible)
• send all tasks from dist-git in one call so we don't have to do git clone/pull for each task in buildbot
• make sending repo urls to buildbot more general - send also repo urls of qa tasks (rpmlint, ...) so we don't have to differentiate between qa and dist-git tasks in buildbot
