![]() ![]() Using it, I got 20,518,802B in about 3 minutes. It also uses around 1.5GiB of RAM with settings I used (a -9 -c)Īfter that was 7-Zip 9.15 beta () using LZMA2. Unfortunately, program is command line only, and not many other programs use that compression algorithm. ![]() Using it, I got 20,132,660B in about 3 minutes of compression. Unfortunately, speed of compression was around 5KiB/s, so it took more that one hour to compress data. Settings used were compression level: maximum. My processor is Intel Core 2 Due T8100 and I have 4GiB of ram.īest compression was with PeaZip using PAQ8O algorithm. Here's what I got after testing various compression methods: I need to have some files transfered (~200MiB) over net and upload speeds here are very slow, so I'd want to compress the data as much as possible. Also, would LZMA or PPMd be better options? I'm thinking about using LZMA2, but I don't know what to set in dictionary size, word size, etc. What settings to use when making 7zip files in order to get maximum compression? I'm compressing PDF documents containing scanned images. ![]()
