data compression proxy

[georgemacin]

Generally speaking most modern compression algorithms give roughly the same compression, and with regard to the number of cores that you can use at once, it is up to you to decide how many you want to use. LZMA2 is highly generally better than LZMA1, if you compress already compressed data.LZMA2 was created for XZ format and it includes changes that are good for that stream compression format. LZMA2 is faster for 4-threads, if you compress big file (more than 256 MB), so 7-Zip will be able to split it to blocks. More about.....7zip
