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:

    Btw, Anand. I was looking for these Athlon IIs at Newegg, and I see an Athlon X2 5000+, 45nm, AM2+, 2.2GHz. Could you ask AMD where this came from. which die this is made from, why it's AM2+ only, etc?

    This is the old Athlons, the k8 generation I believe. The athlon II's and Phenom II's are k10 generation, as well as Phenom I's I think.
    It's amd2+ because am3 wasnt out at the time it was made.

    no, it says 45m, even in AMD's product page. It was quietly launched, but I can't find any reports about it.

    sorry about the double post. The web server claimed there was an error on the 1st post, but apparently it was properly posted.

    Why you are care about this. All AMD products are crap. Period.

    maddoctor, you are a tool and a true idiot. AMD is not crap. Sure I use intel because its faster, but AMD needs to change. I believe you are 100% intel fanboy. Back in 2005, do you know AMD dominated the market? If you say intel is cheaper and better than AMD and you hope that it'll go out of business, then intel will might increase the prices that start at $600.

    Sounds bad huh, doesn't it make you worry?

    Intel Fanboy = FAIL.

    Hey, you are name calling, so just buy AMD's products now if AMD's products are not crap. Even you have admit that Intel products are faster than AMD. You see that, AMD is crap that could not design processor properly like Intel. This is an evidence that Intel's engineers are smarter than AMD.

    They are not crap, and I am not saying I like AMDs. The reason why AMD can't catch up Intel is they gave out rebates to customers and persuaded them to buy Intel cpus. Then EU filed a lawsuit against Intel for hurting consumers and were fined. Have YOU also heard about Intel that they paid dell 1 billion dollars not to use AMDs? You can't say AMD is crap. Do you know AMD makes really good graphics card?

    What EC are wrong in their investigations. Intel is respect with law and did not do anything wrong. Just ask Anand. He will argue with me Intel is not a cheater and did not cheat with benchmark like AMD. AMD products are crap, if you buy it, you will regret wil its slower performance than Intel product.
