7zip vs zip performance difference #320

Any reason why ZSTD (level 11) packing to ZIP is like 5-6 faster than to 7z ? I've compressed same folder (GBs of data) and had like 200MB/s on 7z and ~1200 on zip, same algorithm..

I have no idea where this comes from... Can you verify this also with the cli? Could you re-try this with wtime? And submit your generated values to this issue?

Thought id chime in, although during processing there are occasional peaks, the average for .7z, .zip, and .zstd all being level 11 zstd are 225MB/s, this was using the enwik9 1GB test file
