Speeding Up WordPress on Ubuntu.

  • I’m wondering if I’ve done everything to speed up WP 3.3.1. All my other PHP sites, which are larger than WP run VERY fast! But WP is painfully slow.

    I have a 1 load balancer, 2 web servers and 2 mysql servers (circular replication) at Rackspace. I upped from 256mb to 512mb on each machine.

    The wordpress DB is very small still. I am using HyperDB, so I can’t use super cache… Unless any of you know a way to make that work?

    I am using:
    Memcache, FileCache, DiskCache, Deflate, eAccellerator (5 minutes of cache), Rewrite, multisite, db-optimize, MU Domain Mapping.

    I’ve also done this define('WP_HTTP_BLOCK_EXTERNAL', true);

    My DNS is setup properly.

    My only plugins are db-optimize, Contact Form 7, WordPress MU Domain Mapping.

    In short, everything runs fast, other than WordPress. Which is a shame because I’d like to do almost all of my development in WP.

    Thanks!

    My sites get about 400 unique hits per day.

    Do these apache settings seem optimal?

    StartServers 5
    MinSpareServers 5
    MaxSpareServers 15
    MaxClients 20
    MaxRequestsPerChild 500

    Give this article a read. I was able to make my Ubuntu LTS server more responsive following this advice.

    A lot of that was very helpful. I made some changes, and the server is a bit more responsive.

    But it still seems like WordPress itself is slow. My other sites that are PHP/JS run much faster.

    I’m wondering if there are any other ways to speed up wordpress itself?

    Thanks again!

    Really? I find that a bare WordPress runs well even on poor hardware. With my plugins and theme I’m using W3TC with APC and my install is responsive enough for my needs.

    If you disable all plugins and switch to the Twenty Eleven theme, use ab2 or https://tools.pingdom.com/fpt/ to get a baseline of your blog.

    Then re-activate your plugins, switch back to your theme, and repeat. That should help you identify if you are running into theme/plugin performance issues.

    My main PHP site, which is pretty big and even a bit messy:
    Requests per second: 56.20 [#/sec] (mean)

    WordPress with Twenty Eleven:
    Requests per second: 1.57 [#/sec] (mean)

    For fun, an index.php that just echos “hello world”
    Requests per second: 1183.78 [#/sec] (mean)
    heh…

    They are on the same servers. Very strange!
