![]() Unlike the others, it's a GUI-driven app that covers a number of archive formats and offers other features besides. PeaZip is a little unusual among our selection of archivers. Lrzip manages some reasonable times, good compression and a variety of options, which make it one to watch.Īwesome all-round performance and a great candidate for general us. The real killer is it takes about as long to decompress. The average throughput is only about 170k/second! It's really more of a proof of concept rather than an everyday compression utility, because of the immense amount of time and resources used to generate the files. Nevertheless, we've included figures later for comparison.īy use of extreme measures, it seems to be able to produce the most compact archives. The ZPAQ software is available as a standalone too, but it is messy to build yourself. Whatever the secret sauce added to lrzip, it seems to work as it manages to be far faster than the other LZMA-based utilities on large files.Īs well as LZMA, you can opt to use the LZO algorithms, which are insanely fast, but don't provide a great compression ratio, or the glacially slow ZPAQ, which gives maximum compression ratios. LZMA is rapidly becoming the standard algorithm, in spite of patchy performance with the other utilities that have adopted it. The default method for the actual compression is to use the LZMA algorithms as used by the original 7z and also xz and pxz archivers in this test. This is because it uses some long-range redundancy checks to compare areas of data in the hopes of being able to save some space. The focus here is on compressing large files, and lrzip works best on systems that have large amounts of available memory and big files (greater than 100MB) to crunch. ![]() ![]() Lrzip is relatively new in the world of compression utilities, and is derived from the rzip utility. Mildly disappointing performance from a supposed bzip successor. ![]()
