Hello Adam, Sorry for the late answer. I have been busy.

Reading discussion about polynomial selection (https://lists.gnu.org/archive/html/lzip-bug/2017-05/msg00003.html) I wondered whether better/faster CRC would make a difference in de/compression speed.
Thanks for the suggestion, but I have already tried faster ways of calculating the CRC and I do not think that the (small) increase in speed is worth the increase of portability problems it causes. In line 175 of lzip.h you can find a comment describing my current opinion on the matter:
// about as fast as it is possible without messing with endianness
I also tested lzlib with lzbench (https://github.com/inikep/lzbench) but difference was much smaller. I wonder whether I did something wrong.
Probably not. I have also tried, and most changes that make lzip faster don't work as well (or at all) in lzlib.
Best regards, Antonio.
