Testing FreeBSD

edited July 2012 in Help

I am trying to learn BSD and installed FreeBSD in a KVM. How do I test disk i/o? it seems the command I see here does not run as is. Is it expected that FreeBSD disk io to be much slower than Linux in KVM?

    What version of BSD is this?

  • jcalebjcaleb Member

    FreeBSD freebsd 9.0-RELEASE

    touch test
    rm test

    is dd not the right way to test for bsd?

    DD is not really accurate for other OS as well.

    Thanks @Zen thats encouraging. Honestly, I am lost at the command prompt right now. But it seems it's worth it to work with BSD.

    Yes it is, it is the most stable OS that I have worked with :)

    Thanks. It's a bit discouraging that most commands you know don't work (free, history, etc), and you don't know where to begin. Very tempting to reinstall with very familiar Debian. But I guess I should try and learn BSD.

    Thanks man!

    fdatasync is not a thing in freebsd.

    Enuff said. Ridiculously stable as long as your hardware is stable too.

    Write dd is pretty accurate, doesn't support fdatasync. Read is another story though.

    That's because the BSD DD is different from GNU DD. OS X always comes with BSD DD, however I install GNU DD.

    If you install GNU DD, you should be able todo the standard DD everyone around here uses.

    Too much of a BSD tools supporter. The only time I had GNU tools installed on a FreeBSD machine was due to a major sed that I needed to do quickly across multiple files and didn't want to write a bash or perl script to do it.

  • jcalebjcaleb Member

    I Must learn BSD

  • jcalebjcaleb Member

    Question though.

    If all I want is a webserver for now, would you still recommend freebsd?

  • flyfly Member

    if you don't know freebsd, then no.

    You can have both :P

    The benefits of majoring with FreeBSD instead of Linux 12 years ago is that I've become ridiculously adept at writing perl scripts to do the simplest of things, things that can be done with a single basic linux-included command. :)
