Lunzip vs lzip6/10/2023 (August 1988) algorithm while using a 4K cache footprint. Software-based, table-driven CRC implementations based on the Sarwate "First, a 'slicing-by-4' algorithm doubles the performance of existing Maybe the fair thing to do is to compare hardware acceleration with The case of lzip, the CRC calculation takes about 10-19% of the totalĭecompression time (depending on dictionary size and compression ratio). Take into account that busybox, gzip and lzip use the classical SarwateĪlgorithm because it is simple, safe, and runs on all architectures. Of lunzip vs busybox unxz, enabling crc in unxz (by using xz with crc32) I can cite your own lzip benchmark, when comparing uncompression peformance For compression the speed gain is even smaller. So, even if you accelerate it, the total speed gain is small. Mozilla/5.0 (X11 U Linux i586 en-US rv:1.9.1.19) Gecko/20110420 SeaMonkey/2.0.14īut calculating the CRC is just a small part of the total decompression As you will be decompressing your files and not files you got from a shady part of the internet you would probably avoid that.Re: Selection of CRC32 Polynomial for lzip Although it will still run just fine there is a chance that a terrible security vulnerability may be found in the lzip tools and leveraged by the attackers on the poor souls who use lzip.īut considering that those users may not be the most numerous I think it will be a poor target. 7-zip can also handle xz, but not lzip, even though it's basically the same algorithm.Īlthough there is nothing that will happen in a mere 20 years, let alone 10, that will prevent you running lzip you are correct that as there seems to be only a single developer it may not get as much support in the future. Although I tend to go for bzip2 over gzip anyway. These days I only use gzip for text or when I want to be very quick or compatible with tools like 7-zip on windows. There are plenty of ways to recover from damage and yet still use xz. Lzip claims to have the ability to recover from damage, which is why I liked it, but I would have to give that a test myself. I have never seen a tar.lz file myself but tar.xz is seen widely. I prefer to use xz, even though I like lzips claims xz seems to have gotten a better footing in general use. Nothing will happen to lzip within such a short timeframe. Just make sure to tag the post with the flair and give a little background info/context.
