Exhaustive Data Compressor Comparison

Posted by kdawson on from the pick-one-smaller-or-faster dept.

crazyeyes writes "This is easily the best article I've seen comparing data compression software. The author tests 11 compressors: 7-zip, ARJ32, bzip2, gzip, SBC Archiver, Squeez, StuffIt, WinAce, WinRAR, WinRK, and WinZip. All are tested using 8 filesets: audio (WAV and MP3), documents, e-books, movies (DivX and MPEG), and pictures (PSD and JPEG). He tests them at different settings and includes the aggregated results. Spoilers: WinRK gives the best compression but operates slowest; AJR32 is fastest but compresses least."

  2. [offtopic] Pagination by dotwaffle · · Score: 0, Troll

    This site uses *23* pages. Does anyone else hate pagination? Sure, it has it's uses (decreasing bandwidth consumption) if you're planning on using it as a reference, but if it's an ARTICLE meant for one-off reading, please, for Pete's sake, just use single page format and save us all the hassle of waiting 5 annoying seconds as the next page loads with all your shitty design!

    At the end of the day, if you want to use a "quick link" system to quickly get someone to the conclusion, use this handy thing invented back in "the day". It's called Hypertext - use a hyperlink, use it in a table of contents, and save us all a crapload of wasted time.

  3. AJR32 is fastest by bogomipz · · Score: 0, Troll

    No shit! AJR32 isn't even the name of a program. No wonder it executes fast, and your faith must be stronger than Yoda's if it has any effect on your file size at all.
