The Impact Plugins Have On WordPress Loading Times

Dev4Press has an interesting post that contains performance benchmark numbers that show just how much of an impact certain plugins have on loading times within WordPress. Amongst the 35 tested plugins are bbPress, W3 Total Cache, WooCommerce and a few of the plugins developed by Millan. I as well as many others were shocked to see bbPress with such poor numbers thanks to it loading everything on every page load instead of only what it needs. Keep in mind that it’s not about how many plugins you have installed on your website, but which ones. It only takes one poorly coded plugin to cause you grief.

For some additional reading on how to optimize plugin loading, please see this tutorial by Millan.

  1. Hey I have an idea – bbPress could just use the backend and run standalone so it’s far faster and lighter than WordPress ever was.

    Oh wait, we already had that – it’s called bbPress 0.9 and it was fantastic.

    The tests that are published on that site are kinda useless – no WordPress install operates in a single-page-at-a-time-to-a-single-user – you’d have to test it under load from multiple connections – the impact of one plugin may be a fraction of second but with a dozen connections to the server, some things scale very poorly.

    You also need to test first page load and then second page load to see if the plugin behaves differently and for logged in and non-logged in users.

  2. This is a very important project at Dev4Press, concerning a topic that is very near & dear to me, and should be to most who take an even marginally technical interest in WordPress.

    I’ve been looking at this information and the comments, for days. I have now rescheduled other activities so that I can study Millan’s post & tutorial (and methods & tools) in depth.

    This promises to be a watershed for WordPress.

  3. The plugins benchmarking project being conducted on Dev4Press primarily uses their plugin GD Press Tools.

    That link is to the ‘lite’ version, on the official WordPress Extend Repository. But the Pro version is probably different, mainly in offering better support for multisite, and incuding features of use in commercialized WordPress activities.

    I will be using the standard version, following along with Milan’s post & tutorial, practicing the techniques shown, and noting any differences with the Pro version, for the purposes of benchmarking plugins.

    I also have installed a collection of other plugins which individually achieve parts & pieces of what Milan has done with GD Press Tools. Some of these (also) involve a more or less demanding learning curve, while others are simply ‘constructive eye-candy’, eg Info.
