yum benchmarks

June 18, 2009

About 30dozen people sent me to the test comparing yum to apt-deb. Always a fun comparison. It’d be even more fun if any of the numbers seemed accurate.

I put a short script together for myself – just to see how yum is doing.

Here’s the very simple script:

http://skvidal.fedorapeople.org/misc/yum-test.sh.txt

I ran it like this:

sudo ./yum-test.sh >> /tmp/simple-yum-results.txt 2>&1

Here are my results on my x61s laptop running F11:

http://skvidal.fedorapeople.org/misc/simple-yum-results.txt

Full disclosure. I had already updated the metadata b/c I didn’t feel like testing the network speed in this coffee shop. I also downloaded the pkgs that it installed already by pulling them into the cache with a yumdownloader. Again, I wanted to test yum (and rpm) not the bandwidth of  the coffee shop. I’m running yum 3.2.23-3.fc11 on a 686 install of f11.

Overall the numbers look pretty good to me. Run a test for yourself and point out your results below.

Update enabled repos for the benchmarks

sudo yum repolist
repo id             repo name                                 status
fedora              Fedora 11 – i386                          enabled: 13,289
updates            Fedora 11 – i386 – Updates                enabled:  1,988
repolist: 15,277

    Good stuff Seth. Yum is quite fast these days. Still though, the #1 thing I hear from my Ubuntu-ite friends who try Fedora every now and then is that apt-get is sooooooooooo much faster.

    Is the Debian/Ubuntu metadata somehow kept much smaller? I do admit, yum itself is fast and most of my waiting is done when metadata has to be pulled in for filelists or other reasons.

    But I would assume this happens on the apt-get side as well?

  2. skvidal Says:

    debian does not have file-based-dependencies. So the complete filelists are never necessary for depsolving. So, in short, no, debs do not have this metadata.

    If you’d like to lead the charge to forever get rid of file deps in fedora/rpm please go for it.

    • Ray Says:

      Makes sense. I wonder how large of an undertaking this would be?

      Definitely didn’t mean to come across as overly critical btw. I’m perfectly happy with yum and thumb my nose at those silly Ubuntu users ;-)

      • skvidal Says:

        No sweat. If you want to see how many file deps there are try this command:

        repoquery -a –requires | grep ^/ | sort |uniq

        just as an example

  3. jef spaleta Says:

    For information which repositories were enabled during that run and what was the number of total package count across repositories? Even duplicates..as duplicates sitting in multiple repository branches still show up as metadata that yum needs to parse..or am I wrong about that? I’d like to understand the benchmarks as a function of repository/metadata size if possible.

    Your comment about network speed I think is an important point. My real concern with comparative benchmarks associated with yum and apt has always been about methodology concerning the testing of comparable operations. I think people make bad assumptions as to when and where yum and apt are doing network io.

    I’d like to see a methodology described that ensures a comparative benchmark for comparable operations and excluding network io for both applications.

    well, on my dual core am2/2800, the times from your script were all very small. however, i’ve just seen a bunch of updates coming down the tubes, so i timed the yum update on my x40 notebook:

    real 16m30.296s
    user 3m57.293s
    sys 0m33.789s

    the first part, downloading included, was

    Total 239 kB/s | 52 MB 03:41

    so how is that a 33 seconds process ends in a 16.5 minutes time wasted?

    i confess this really is above my understanding in this very moment :)

    • skvidal Says:

      Did you capture the output from running that script? If so, please post it – it’ll help in showing where time is being used. Though with a number like 16m I suspect it’s all network time.

      • cornel panceac Says:

        no, it was a simplified version, just

        time yum -y –disablepresto update

        the output was this:

    so if 3:41 was spent downloading and you had 16m total I’d bet about 11:30 of the remaining 12ish minutes was in the rpm transaction. Feel free to confirm them by running:

    yum -d 3 update

    the next time you have an update to run.

    but if you get a chance – run the actual test I posted, not something else entirely.

  6. skvidal Says:

    A couple of more. These are both the 2nd or 3rd runs after downloading the pkgs:

  7. These comparisons are always interesting. :-) Good stuff.

    As an aside, I always think one thing that gets overlooked in the yum vs. apt discussion is just how nice, clean, and informative yum’s output is compared to apt’s.

    Thanks for all the hard work, Seth.

      It hasn’t been just my hardwork for quite a while other folks who deserve ENORMOUS thanks for making things so much better:

    I’ll run this test when I get a chance and post the results, too.

    I would also be interested to see if the results change if you reboot between each test?

    • skvidal Says:

      I’m sure there are benefits from having a hot rpm cache – but to replicate actual uses of yum rebooting between each test isn’t helpful. People don’t run: yum list updates; then reboot then run yum update. They run them together.
