Speeds depend on data as well. Try Silesia dataset first.

Oh, that'd be it then. I must have overlooked the bit where you mentioned the Silesia dataset and skipped straight to enwik9. With that corrected, I get similar results to yours.

One issue I did notice during testing is that lzav's compression ratio is fairly unimpressive (~42:1) on all-zero data. Surely it should be able to do better than that?

Ah, yes, I'll recheck the constraints regarding such all-zero data, easy to fix.

You may check lzav 1.4 out, all-zeros runs should compress twice better.
