Some speed tests of new versions of par2/unrar

SABnzbd, osx Add comments

I’ve made some quicks tests with latest unrar binary and Macpar Deluxe par2 64 bits binary :

This little script can help you to do the same tests and compare times with binaries included in my last build… if you want to play.

#!/bin/sh
FILE="folder/some"
echo "Repairing with new par2 64bits"
#removing some parts to have something to repair
rm $FILE.r0[01]>/dev/null
time par2/par2 r $FILE.par2>/dev/null

echo “\nRepairing with old par2 32bits”
#removing some parts to have something to repair
rm $FILE.r0[01]>/dev/null
time par2/par2old r $FILE.par2>/dev/null

echo “\nUnraring with new unrar 3.70″
time unrar/unrar e -o+ $FILE.rar>/dev/null

echo “\nUnraring with old unrar 3.66 beta”
time unrar/unrarold e -o+ $FILE.rar>/dev/null

Results : with my config (macbook pro santa rosa 2.4Ghz with 2Go Ram), there no signiticative speed improvements…

a zip file that contains everything needed to test is available here

    Hello,

    I tried to compile 0.4 without any luck, I hope that you’ll be able to do it ;-)

    for next release, can you release a par2 multicore ?
    speed tests seems promising ;-)

    I’ve had a go at compiling the source.
    This is a Tiger build it should work on Leopard, if it works at all.
    But if you want a Leopard build just run ‘python setup.py py2app’ from within the source folder.
    You’ll find the app in the dist folder after the build is complete.

    Please read the relase notes and forum post before updating.

    This is the first time I’ve edited the source files to be OS X compatible by myself so there could be errors, so you have been warned.

    using your script on a 2008 Mac Pro 4-core with a DVD sized Wii game missing 2 50 MB parts, my findings are the par 64-bit version as part of the MacPar Deluxe package is the fastest:

    MacPro:speed_test echuige$ ./speedtest.sh
    Pepairing with MacPar Deluxe par264
    rm: uga-abt-f/uga-abt.r0[01]: No such file or directory

    real 0m57.662s
    user 0m52.723s
    sys 0m9.658s
    Pepairing with MacPar Deluxe par232
    rm: uga-abt-f/uga-abt.r0[01]: No such file or directory

    real 1m4.988s
    user 0m55.237s
    sys 0m9.844s
    Repairing with Intel optimized thread db 64bits
    rm: uga-abt-f/uga-abt.r0[01]: No such file or directory

    real 1m7.353s
    user 1m13.101s
    sys 0m5.583s

    Repairing with old par2 32bits
    rm: uga-abt-f/uga-abt.r0[01]: No such file or directory

    real 1m5.050s
    user 0m56.090s
    sys 0m9.975s

    The intel thread optimized version performes even worse than the par executables you provided, which show no real difference (your new 64bit version not shown)

    it’s strange… I’ve made some new tests with intel optimized and with my conf, i get better results… 30% timeless… and no significative improvements with the macpar par2 64bits…

    How much RAM do you have ?

    I’ll soon update my config with 4 Go and replay some tests…

    Anyway thanks for testing and sharing results !

    Hi rAf,
    I use 4 modules of 1GB, but this has nothing to do with the results produced. In order to do a “real world” test, many of the .rar parts have blocks missing. I had too few repair blocks, so actually only verification was done. This is heavily disk based. This explains why the results were so close.
    I will redo the testing properly and report.

    Greetings,
    B Wats

    Hi rAf,
    As it turns out, the difference is rather dramatic indeed:
    10 vs. 23 real mins!
    I tested the latest Intel Threading Blocks optimized version by Vincent Tan vs. the MacParDeluxe 64bit version on the same fileset. The Intel version cuts time in more than half.

    With the intel optimized version, CPU hovers around 300% (showing 4 near full bars), whereas the MacPar version shows around 30% CPu usage.
    Also, there is a difference in disk access: the MacPar version writes 15MB/sec spikes, while the Intel version show fewer spikes of around 55MB/sec, reading about 9 MB/sec. I use a decent near empty WD 500 GB 16MB cache drive in Bay 3.

    Below is verbose output, MacPar version first:

    So we agree that the intel optimized one is the best choice…
    Thanks for your testing and reports again.
    I’ll update the main post soon.
