Shawn Pearce 21e4aa2b9e Split delta search buckets by byte weight Instead of assuming all objects cost the same amount of time to delta compress, aggregate the byte size of objects in the list and partition threads with roughly equal total bytes. Before splitting the list select the N largest paths and assign each one to its own thread. This allows threads to get through the worst cases in parallel before attempting smaller paths that are more likely to be splittable. By running the largest path buckets first on each thread the likely slowest part of compression is done early, while progress is still reporting a low percentage. This gives users a better impression of how fast the phase will run. On very complex inputs the slow part is more likely to happen first, making a user realize its time to go grab lunch, or even run it overnight. If the worst sections are earlier, memory overruns may show up earlier, giving the user a chance to correct the configuration and try again before wasting large amounts of time. It also makes it less likely the delta compression phase reaches 92% in 30 minutes and then crawls for 10 hours through the remaining 8%.
