    Default Apache2 mod_proxy bevaiour change since OS 10.3 ?

    Dear Forum,

    though i am not 100% sure, that is the right forum, and if it is perhaps too specific:

    We have migrated a Lucene (Regain) / Apache .htaccess setup (Lucene Port 8020 -> Apache2 Port 80) from OS 10.3 to OS 11.3, but have a massive decrease of access speed - it seems the results from the search engine "drip" with the OS 11.3 setup via the :80 port - in comparison in OS 10.3 they are lightning fast. Tests on the non-url-rewritten "Pure" 8020 port of the Regain-search engine have the same speed.

    So our question: was there a systemic change how Apache2 in OS11.3 works than in OS10.3?

    Thanks a lot for any help.

    Best regards

    David

    this is primarily a forum of volunteer _users_ helping needy
    users...that is to say, i think you might need to chat with some of the
    hackers/developers of Apache or (maybe) openSUSE...see, i guess as well
    as moving to a new version of openSUSE you also moved to a new version
    of Apache, right?

    wait! when you say "OS 10.3" do you intend to write openSUSE 10.3 or
    SUSE Linux Enterprise Server 10 SP 3?? there is a big difference, first
    being that SLES is a commercial product supported by the good folks at
    http://tinyurl.com/422mrnu

    your ID/Pass here works there..

    you can learn exactly what version of which operating system you have by
    returning the output of
    Code:
    lsb_release -a
    to this thread..

    if running openSUSE i would suggest you next get with our hackers via
    IRC and/or mail list, how to do that is noted here:
    http://en.opensuse.org/openSUSE:Communication_channels

    but, if in fact it is an Apache change perplexing you, you may be best
    off just going straight to the Apache folks, or their documentation,
    release notes, etc..

    but, none of the above means you might not get lucky and a guru happens
    through with a perfect answer...so, you are very welcome to hang out, or
    come back from time to time to check!!

    sorry, i'd be more helpful if i could

    Hi David,

    There have been significant changes to the various Apache proxy modules over the years, and it sounds like perhaps you were running a significantly different (older) version of Apache and proxy.

    A few things I can think of to check: It looks like you are using just mod_proxy and not mod_proxy_ajp correct? (You can see what you are using with an a2enmod -l and by looking at /etc/sysconfig/apache2 )

    You may find trying a different proxy may yield different results.

    As a radical option, you could try nginx as a proxy, it gets a lot of attention these days for its performance, though to be quite honest you should be able to get Apache performing with similar results as you had before.

    You can also try setting using LogLevel debug and see if it yields any additional info that may help you identify the problem.

    Cheers,
    Pete

    Dear colleagues,

    thank you for the fast response. I will try to recheck over the weekend. Nginx sounds like an option. And yes: it was the good old (and veryyy solid OpenSuSE 10.3 ...).

    Thanks

    David
