LZ4 VS 7-Zip-zstd

LZ4 is a bit more complicated, but seems faster: https://github.com/lz4/lz4/blob/dev/doc/lz4_Block_format.md

According to these https://github.com/lz4/lz4 values you need around ten (10) quite modern cores in parallel to accomplish around 8GB/s.

The popular NoSQL database Cassandra utilizes a compression algorithm called LZ4 to reduce the footprint of data at rest. LZ4 is characterized by very fast compression speed at the cost of a higher compression ratio. This is a design choice that allows Cassandra to maintain high write throughput while also benefiting from compression in some capacity.

Yeah, sure, when you have monster core counts. on regular systems, not so much, here's from their own github page. it achieves, eh, 5GB/s on memory to memory transfers, i.e. best case scenario. so, uh, no? i'm not even sure it's any better than the CPU decompressor one Nvidia used.

> The downside of lz4 is that it can’t be configured to run at higher & slower compression ratios.

lz4 has some level of configurability? https://github.com/lz4/lz4/blob/v1.9.4/lib/lz4frame.h#L194

There's also LZ4_HC.

Since nobody mentioned it, I'll add lz4 (https://github.com/lz4/lz4).

Do you consider rar a standard? It's a pretty good format, even though there aren't any good open-source implementations. But if you're willing to pay for your software, WinRAR command line versions are available for most platforms.

7zip is the most obvious free alternative. There is also a 7zip fork that offers zstd [1]. The command line experience for 7zip isn't very good however.

There's also this fork which supports additional compressions: https://github.com/mcmilk/7-Zip-zstd

7-zip is actually not a bad option, but I'd strongly advise using the fast-lzma2 codec, because, well, it is waay faster, and might even give you better ratios, depending on how you use it. You can find an implementation here, and it is compatible with traditional 7-zip (you can decompress it on any computer with any newish version of 7z)

Hi, PeaZip can use McMilk's additional compression codecs for 7z format (Zstandard, Brotli, Lizard, etc), https://github.com/mcmilk/7-Zip-zstd

You can extract the files yourself with 7Zip. You can install 7Zip from here and then install this plugin to extract ZStandard files, or you can directly install the modified 7Zip with the plugin already from that plugin page. Then simply open the zst file you downloaded with 7Zip and extract it.
