WP Super Cache - The Ultimate WordPress Caching Plugin

ocaoimh.ie — Tired of clicking a link off the Digg front page only to find a crashed or mortally lagged site on the other side? Finally, Donncha (one of the main WordPress developers) has solved the problem once and for all with a plugin that blows WP-Cache away.

  • suxmonkey, on 11/08/2007, -1/+22This sucker is amazing ... I've been talking to one of the guys who tested it. Should be smooth sailing for sites that hit the front page of Digg or SlashDot. Say goodbye to clicking the frontpage only to find some crap-hosted crashed WordPress weblog!
    • kingkilr, on 11/08/2007, -2/+13The real question is why isn't it built in in the first place?
    • appletalk, on 11/08/2007, -2/+7I think this should be included as a default plugin, along with Akismet.
    • darkfate, on 11/08/2007, -3/+5They like to keep the distribution as light as possible. Not everyone needs this since a lot of WP sites are actually hosted on good servers, or don't warrant the need for it since the amount of traffic they get is minimal.
      • kingkilr, on 11/08/2007, -1/+8So your suggestion is people overbuy servers instead of writing decent code?
    • Archon810, on 11/08/2007, -0/+2Here's the straight svn checkout:

      cd ......./wp-content/plugins
      svn co http://svn.wp-plugins.org/wp-super-cache/trunk wp-super-cache

      Then to update to latest version, just cd wp-super-cache; svn up
  • jpozadzides, on 11/08/2007, -2/+23This is without a doubt the biggest advance in WordPress performance in years.

    Donncha has not only improved the existing ubiquitous WP-Cache system for users that are logged in (bug fixes, added plugin capabilities, etc), he's literally invented a new methodology for static caching of documents for visitors which renders at least a 2-3X performance improvement over WP-Cache.

    Every WordPress blogger on the planet WILL BE using this plugin for a long time to come. It is truly revolutionary.
  • stronglifts, on 11/08/2007, -1/+13Just installed, works great. It's indeed much faster than wp-cache. Great plugin.
  • rupertmorris, on 11/08/2007, -3/+29This should be ROLLED INTO WORDPRESS so that all sites are almost-digg-proof.

    As should be the automatic upgrade plugin.
  • bamafun, on 11/08/2007, -2/+8wow ! Page load rate is fantastic !! Better than ever ! Thanks!
  • MikeonTV, on 11/11/2007, -0/+23Lets get this to the front page and test this sucker out!
  • apachehtaccess, on 11/06/2007, -1/+2Great, this is really great! Also like the header idea at askapache - http://www.askapache.com/wordpress/wp-cache-speed- ...
  • dominoman44, on 11/08/2007, -4/+2Great tip and an awesome plugin
  • jimbeaug, on 11/08/2007, -3/+1WOW!!! How cool is this??
    • masterc, on 11/08/2007, -0/+8Apparently cool enough that you need three exclamation points and two question marks to illustrate your point.
    • econofast, on 11/11/2007, -0/+5It is 99.8% cool.
  • GeeksAreSexy, on 11/08/2007, -2/+12I never understood why the Wordpress developers aren't developping a built-in cache inside their blogging platform..
  • TomRaftery, on 11/07/2007, -2/+0Ooooh, I can't wait to try this on my blog
  • devzer0, on 11/08/2007, -1/+3Two questions:

    - anyone done any prelim testing vs. eaccelerator?
    - might this be compatible with eaccelerator?

    The one 'caveat' I hate is that if you're logged in or have left a comment, you're SOL.
    • 32bitwonder, on 11/08/2007, -0/+3I've used WP Cache and eaccelerator together for quite some time without issue. After a very quick test, WP Super Cache also appears to be compatible.
  • reconbot, on 11/11/2007, -0/+5IT looks like it saves the gzipped output to a file and uses an htaccess and modrewrite to check for the cached file first and just serves it up. It also has hooks for plugins to invalidate the cache if necessary. Cool.
  • dxplus, on 11/08/2007, -1/+0dugg for very awesome plugins
  • MalDON, on 11/08/2007, -1/+1There's a problem with he script. I installed it, did all the configuring, and in the admin page it says do_cacheaction() not a function. I did some digging and in the wp-cache-phase1.php file, do_action is there, so maybe the file isn't being included into the wp_cache page properly.
    • froman118, on 11/08/2007, -0/+2Did you rename wp-cache-phase1.php to advanced-cache.php and put it in wp-content?
      • MalDON, on 11/08/2007, -1/+1you know, that might help :p
      • MalDON, on 11/06/2007, -0/+1Gah, still not working. I guess I'll have to hack it all together later.
  • perot9296, on 11/08/2007, -5/+0If you have $7 hosting your site will still go down, it just might make it to 175diggs instead of 90.
    • chrismgtis, on 11/06/2007, -0/+1Oh really now? Hosting is cheap these days. You don't need to pay to handle Microsoft.com traffic these days unless you do actually get a couple million hits a day.
  • Twister47, on 11/06/2007, -0/+4Anybody benchmark the two (WP Cache and Super Cache) yet?
  • anthon1, on 11/08/2007, -0/+4Super Cache me Bro!
  • donncha, on 11/08/2007, -0/+2I benchmarked it very quickly last night, and the super cache plugin served twice as many pages per second as wp-cache, without compression. It was a closer tie when compression was enabled, but I'm also using an xcache plugin too which makes WordPress much faster.
    Tests were done in the same datacenter. The effect of a slow connection cannot be underestimated. A slow user will really hurt your site!
  • Apreche, on 11/11/2007, -2/+9Caching like this can help, but it is not necessary. My WordPress got dugg up last week, and it had no problems whatsoever. The real problem is people with crap hosting. People get $5 a month shared hosting with almost no resources, and then they go down. It's not the fault of WordPress. For many of these people, even caching won't keep their site up. Lesson to learn is that you get what you pay for. If you want to be able to handle more listeners, you have to get better hosting.
    • Nightfall, on 11/09/2007, -0/+2Thumbs up for accuracy. Well said and very true.
  • lazyfisherman, on 11/06/2007, -0/+1oh god please yessss
    wp-cache has needed an upgrade for a long time

    Does anyone know if this works with Wordpress on Windows Hosting?
  • k8cpa, on 11/07/2007, -0/+4Guys, I'm using it here and I don't get much traffic, But it makes the blog load a WHOLE lot faster. It's nice, get it... reason why it's not going to be built in, it doesn't work on ALL hosting servers. Dreamhost won't run it, for some oddball reason.

    -Chuck

    • reconbot, on 11/06/2007, -0/+1I'm sure you can make it work on dreamhost
  • 0KonTroL0, on 11/07/2007, -0/+2Everyone please digg so we can see the results....
  • fak3r, on 11/06/2007, -0/+1Installed this last night after updating my WP install, it works, nice. Next to try it out with eAccelerator, should be fine though.

    Oh, and anyone who runs a server should have Varnish installed to do http acceleration - it really works, and with this plugin, don't worry about things anymore, the server can handle it.
  • UnicornNinja, on 11/07/2007, -1/+1I'm guessing this won't work on IIS hosting because of the .htaccess requirements, but has anybody given it a shot before I waste my time with it?
  • chrismgtis, on 11/09/2007, -2/+3Fatal error: Call to undefined function: do_cacheaction() in /wp-content/plugins/wp-super-cache/wp-cache.php on line 172.

    Nice. Back to the drawing board.
    • mulicheng, on 11/08/2007, -1/+1I got that too. Digging parent up so somebody will suggest the fix so I don't have to dig through the php code myself.
    • mulicheng, on 11/08/2007, -0/+3I found the answer on the wordpress plugins database faq page for the plugin. If you are upgrading from wp-cache to this, you probably need to re-create your wp-cache-config.php and advanced-cache.php files in the wp-content directory to point to the new plugins files instead of the old wp-cache files.
  • anthonylawrence, on 11/06/2007, -0/+1About damned time someone came out with this.........

    Cant wait to test it out just to see the load times on my blog now!
  • jorgepblank, on 11/06/2007, -0/+1This is simply amazing, it has boosted my site's speed manifold, wp-cache really needed an upgrade. Only problem is that the author says he just 'tagged' 0.3, but I don't see 0.3 available anywhere, maybe the cache hasn't updated? :P
  • chaoskaizer, on 11/07/2007, -0/+1a fork of wp-cache with extra features does sound interesting but there is no real benchmark yet.
    • jorgepblank, on 11/07/2007, -0/+1759 diggs, and the page loads near instantly, and you say that's not good enough proof? There isn't a scientific hard ass benchmark yet but in my book this is enough to prove it ten times over. If you don't believe that, read everyone else' testimonies.
  • ravetildon, on 11/07/2007, -0/+1Looks like it's holding up for you with the Digg. :) I just put it on my blog also! Thanx for a great addition to the blogging community!
  • jstroh, on 11/08/2007, -0/+1Christ finally one that works with plugins.
  • bazil749, on 11/08/2007, -0/+0Works fine for me on DreamHost, except for the compression.
  • Kaelos, on 11/08/2007, -0/+1Definitely going to install this! The original wp-cache used to give me major errors...
  • mulicheng, on 11/08/2007, -0/+1The readme file for the plugin says if your browser asks you to save the file, that you need to disable super cache compression. I wasn't satisfied with that answer and posted a solution here: http://allmybrain.com/2007/11/08/making-wp-super-c ... This is for Apache. You have to be able to edit your hosts configuration file but it fixes the problem.
  • rooseve, on 09/12/2008, -0/+0There's a new cache plugin, WP Widget Cache, which can cache the output of your widgets. It significantly reduce the server usage especially when Google is crawling your site, a plus for WP Super Cache
