There is a difference - increaing slots, which I presume is (more) buffering, decreases time. > I think it could be because lzip buffers the decompressed output in blocks of 32 MiB (dictionary size in the files you are testing) while plzip buffers the decompressed output in blocks of 1 MiB. I don't think this buffer is that big. Manual says default value for of --out-slots is 64 for plzip. That would mean they bot have similarily big output buffer, but the difference in time suggests the output buffer for lzip is much smaller. You may want to have a look at logs in attachment.
