PAR2 Multithreaded Archive Recovery Performance

Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive

Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.

WinRAR - Archive Creation

Our WinRAR test simply takes 300MB of files and compresses them into a single RAR archive using the application's default settings. We're not doing anything exotic here, just looking at the impact of CPU performance on creating an archive:

    by any chance you're a Intel worker? you sound like you do.

    Intel did not do that. All the given evidences are false and could not prove anything.

    "no competition to keep prices low"

    [sarcasm] Thats right, if only there was no COMPETITION prices could be LOW... it is a well known FACT that competition serves only to raise prices! [/sarcasm]
    That is the dumbest thing I have heard in a very long time.

    wow. Way to fail at reading comprehension.

    The man is say if there was no competition there would be no reason to keep prices low. He was saying "if there was no competition to keep prices low, intel would raise prices"

    So lets read next time before we call anyone else stupid.

    Not quite... at least, not in my opinion.

    On page 6, maddoctor posted:

    "Whatever AMD product throws to market, rubbish is a rubbish. Intel products prices will make AMD's prices room tighter, and AMD is going to sink into oblivion. I love it because Intel prices will be cheaper to consumer."

    I may have misinterpreted this, but his post seems to be indicating that if AMD were no longer in the game, Intel would have no competition and would LOWER prices in accordance. Something which, as we all know, not only wouldn't happen but is totally contrary to common business practices. If there's only one supplier, you're not going to go find cheaper options from somebody else; you'll be tied to that one supplier and they will feel less need to improve their designs.

    As odd as it may seem, that's what I believe he was referring to.

    You do fail at reading comprehension.

    Interesting statement to make when you fail to back it up.
