It's hard to say without some profiling to find the bottleneck. Benji has only seen limited benchmarking and performance tuning and my use case has relatively small volumes and the change rate is small too, so it isn't a priority for me at the moment. If someone with experience in Python profiling would look into this, I'd be willing to help interpret the results and work on a solution.
You could also try to look at the debugging output to see if you can deduce something from it. The reading and writing of blocks should output some time measurements.

Ok, ill see what I can figure out, but this is definitely a bit over my head.

On a side note, is it possible to use a "hints" file with LVM, similar to Ceph/RBD? I see it mentioned in the documentation as possible, just not sure how it would work? I don't think I can point rbd-diff to a lvm volume?
