    Apache 2.2.8 & High CPU Load

    Just wondering if anyone has had problems with high cpu load after upgrading APACHE to 2.2.8. We were running 1.3.5 with comfortable CPU loads of 2-10 on dual Xeon 2.8's. Now the loads are 20-70 with most of the CPU being used by many many httpd processes. I've heard that APACHE v2 does consume more resources, but am wondering if there was a problem with the build, or is it that much more demanding.

    OTHER INFO:
    WHM:11.15
    CPANEL: 11.18
    OS: CENTOS 4.6
    KERNAL: 2.6.20.4-ts.grh.mh.i386

    Thanks,
    Zenon

    You may want to remove unused modules if you are having load issues. We run Apache 2.2.8 with no problems, it improved performance over 1.3.

    I have already unloaded a couple of modules that are no longer being used. I posted in another forum asking about the clamav plugin is it worthwile to have loaded? I have one server running it and two not running it. Ive had no problems with the two that aren't running it and was wondering if I should leave it loaded or not. The only other plugin that is running is the MUNIN service monitor.

    I find it unusual that the process "/usr/local/apache/bin/httpd -k start -DSSL " has multiple instances running at 5-40% cpu. that process shouldn't consume that much resource should it? My other servers running 1.3.5 use about 2% per instance of "/usr/local/apache/bin/httpd -DSSL "

    What does the "-k start" mean in the process from version 2

    So an update, got the load problems resolved, most of the problem was with an update to PHP5 only support. Sites that were still trying to use PHP4 especially with wordpress were stalling on load and never finishing or terminating. Once we got everyone PHP5 complaint load issues were resolved.
