Encryption Benchmarks

Finally, our favorite part of any Linux benchmark - hashing and encryption tests. Below, you can see how John the Ripper fared under various compilation options with the various processors that we had on hand.

32-bit John the Ripper 1.6.37 - DES [64/64 BS]

32-bit John the Ripper 1.6.37 - MD5 [32/32]

32-bit John the Ripper 1.6.37 - Blowfish (x32) [32/64]

Below, you can see how our processors performed in the OpenSSL "speed" benchmark. You may download the full printout of an Athlon 64 3800+ speeds here or the Pentium M 2.1GHz with 533FSB.

32-bit OpenSSL 0.9.7d - AES-128 CBC 1024byte

32-bit OpenSSL 0.9.7d - RSA 1024bits

Performance on all encryption benchmarks was only average. The Dothan keeps up with all processors in the same price range, but it does not out-perform the category leaders in any test.

    Does anyone know where I can buy socket479 dothan core pentium Ms online? Newegg and various other places stock the socket 478 variety, but I haven't found anyone that has the socket 479 type.

    If you are using an IDE drive make sure DMA was enabled. To check you can use the hdparm command.

    Something is disasterously wrong with your setup. Have you tried using a live CD and try compiling with that?

    What command are you using to compile the kernel? Are you sure you have GCC installed correctly? What do you get if you type gcc-config -l?

    Are you sure nothing else is running (well major tasks)?

    Have you tried running it as root?

    Correct they are "user". Here are the results with GCC 3.4.3 on the same system on the second run.

    real 20m42.192s
    user 16m39.148s
    sys 1m21.287s
    dave:~/bench/gcc/linux-2.6.4 # cat /proc/cpuinfo | grep MHz
    cpu MHz : 2105.068

    ... Not sure what is the problem here. The CPU clock is correct. If anyone else has any ideas as to why only the GCC benchmark would be affected I am all ears.

    Results with gcc version 3.4.3 20041125 on the Banias 1.7GHz (DDR266/400FSB).

    run 1:
    real 4m40.758s
    user 3m58.039s
    sys 0m20.060s

    run 2: (after "make clean")
    real 4m24.759s
    user 3m58.409s
    sys 0m19.978s

    run 3: (again, after "make clean")
    real 4m27.728s
    user 3m58.233s
    sys 0m20.161s

    Of course, this is with gcc 3.4.3. I'd rather not install 3.4.1 on this system only to rollback to 3.4.3 straight after.

    I assume the kernel compile times you showed in the article were from "user" (or user + sys), rather than "real", as the latter is affected by other things happening on the system whereas the former gives the actual CPU time taken by the process.

    The results are impressive to say the least. It's certainly extremely puzzling that your results with Dothan were so disparate. One would expect it to do very well indeed based on my results with 1.7GHz Banias + DDR266.

    For comparison, my 3GHz NW P4:
    run 1:
    real 4m50.687s
    user 4m19.365s
    sys 0m25.261s

    run 2:
    real 4m46.675s
    user 4m23.775s
    sys 0m24.567s

    Yozzo, Can you please do kernel 2.6.4 like we did in the benchmark?

    Development on the 3.4 gcc branch has only recently stabilised, and the pentium-m cflag was indeed quite buggy/broken in earlier releases, hence why I stated that gcc 3.4.1 is "pretty old". Not in the absolute sense, but rather in terms of the amount of development work that has gone into the 3.4 branch since.

    Some quick benchmarks with gcc version 3.3.4 20040623:
    System was P-M Banias 1.7GHz, 768MB DDR266, i855PM; on a Dell D600.
    # time make
    ...
    real 9m36.940s
    user 8m40.395s
    sys 0m39.643s

    2nd run:
    real 9m35.056s
    user 8m40.515s
    sys 0m39.664s


    For comparison, my 3GHz NW P4, 1.5GB DDR400, i875P:
    1st run:
    real 10m0.508s
    user 9m0.929s
    sys 0m46.210s

    2nd run:
    real 9m58.564s
    user 9m3.107s
    sys 0m45.658s

    Kernel was 2.6.10-ck1-nitro1, with custom .config (http://homepage.ntlworld.com/yaoyaoliu/.config).

    I didn't have gcc 3.4.3 available on my laptop to test, but gcc 3.3.4 clearly shows the expected performance and hence that there is nothing inherently wrong with the P-M architecture that makes it slow at compiling -- indeed, the 1.7GHz Banias P-M (DDR266, 400FSB) is slightly faster than my 3GHz Northwood P4 (dual DDR400, 800FSB).

    I was also interested to see how much faster gcc 3.4.3 was compared to 3.3.4, and so decided to do a compile on my 3GHz P4 desktop machine (same kernel):
    real 6m34.443s
    user 5m52.910s
    sys 0m33.019s

    Interesting results indeed.

    The GCC we used is the same GCC bundled with SUSE 9.1, our test platform. I don't think 6 months is too old for a processor architecture that has been available for close to 2 years. However, we will get a chance to revist these numbers in the very near future, and i will redo the tests with GCC 3.4.3 and GCC 3.4.1

    Hope that helps,

    http://gcc.gnu.org

    The GCC Homepage:
    3.4.1 released July 2004
    3.4.3 released November 2004

    If you look at the changelist there have been a lot of improvements even between these few releases.
