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:

    Currently, Intel does not need any competitor. Intel will crush them as soon as possible with prices cutting. This is their own fault, why they are not so competitive in performance and can not wins the benchmark

    Because they've done this so well with AMD for the last 20+ years... great logic little boy...

    I am sure this joker has no idea about computers. If only designing GPU chips and killing competition was so simple.

    Tell you what, consider these two facts;

    1. Intel has been trying to kill AMD for last 40 years and still trying

    2. It took intel 5 years to add Northbridge in the die after amd did that in 2004.

    Tech forums are no paradise for jokers. Go home and sleep well

    1. Intel isn't trying to kill AMD, they are trying to shackle AMD into the budget range and keep them there, AMD sole purpose is to remain as a second supplier and to give the appearance of competition, so for Intel AMD serves a purpose.

    2. Intel didn't care about having a memory controller on their processors as they were already outperforming AMD's offerings without it. It isn't the be all and end all to performance and also comes with disadvantages as well. Core 2 outperformed Athlon 64's of the time, and were even to equivalently clocked 45nm Phenoms, 65nm AMD had it's own share of issues.

    What Intel never trying to kill AMD. This is only AMDiot assumption. Ask Anand, he will never agree with you AMDiot. This is the nature of capitalism. Money and product competitiveness are the facts that you can not denied.

    Shitty pun, knock it off. Intel has tried to crush AMD since 1986. Where have you been? Oh, right, you probably weren't even born when the 8080 and 8086 processors came out for the IBM PC or even when the AM286 came out.
    Money, product, and competitiveness are not facts they are words you just threw out to sound like you know something. You have no clue about business, go back to your 6th grade classes.

    "2. It took intel 5 years to add Northbridge in the die after amd did that in 2004. "
    Do you mean memory controller? But, BTW, Transmeta was able to put northbridge into the die back in 1999.

    There is so much wrong with your post it's not funny, but I'll point some out.

    1) We have no idea how Larrabee will perform.

    2) nVidia ATI/AMD are not going anywhere soon.

    3) Intel got beaten by ATI and nVidia in the Graphics card market before when Intel released the Intel i740i AGP graphics card.

    4) With Intels history of poor driver support for there Graphics solutions, I don't have much faith in Larrabee being different, I hope I'm wrong though, the added competition would be awesome.

    5) If Intel owns the Chipset/CPU/Graphics markets 100% that would be -bad- no competition to keep prices low, remember when a decent computer would cost over 3 thousand bucks?

    6) Both ATI and nVidia have had YEARS of experience in the Graphics industry, they will not let a new player into that market without a fight.

    7) I would -not- be happy if we lost any extra company's especially AMD and nVidia, it would be all-round bad for everyone, I wouldn't have been able to build a stupidly cheap Quad-Core system (Athlon 2 x4 620) if it weren't for AMD.

    >>remember when a decent computer would cost over 3 thousand bucks?

    I wouldn't mind paying $3000 for a decent computer, but please remember that even an undecent one would have set you back $1500 back then, while nowadays you can buy a $500 AMD rig
