The Go version was getting about a 25x speedup when using FindSequencesOnDisk (which makes use of all of the other facilities) . The parsing and string building of the paths, frame ranges, and results are faster. I reuse buffers instead of constantly allocating new strings. Also the find operation is concurrent. An example was that my co-worker was using the python version to drive a graphical file sequence browser. He saw that massively apparent speedup in the interface when he switched to the Go version.
