This is actually a good idea. In practice, the shards are swamped by the amount of builds today, and the throughput has been close to 1/h a long time, even with work ongoing to prune or tighten stupidest IGT tests. We could make the shard run requirements stricter: in addition to passing BAT it would need some amount of Acks. Patchwork already collects them. Another idea has been moving the serialized shard run queue to something that can handle reordering: trybots can be moved after everything else. This doesn't affect to the shard queue length though, if we still want to test everything. > Additionally, there are smaller optimizations to be made (obviously all > depending on developer bandwidth to implement this stuff), such as > identifying patches that don't change the resulting binary > (comment/documentation/whitespace changes), and only running build > testing on them. This idea has been floating around, and would help in 5% changes or so (which is still noticeable: 1-2 more builds / day tested instead of queued). Just need a good diff checker that says "text changes only, skip it".
