DiggProof your Wordpress

Note: This post is over 3 years old. You may want to check later in this blog to see if there is new information.

I know, it’s a ballsy headline, but I’m tired of hearing all of the script kiddies on Digg scoff at Wordpress, blaming it for sites crashing from the “Digg Effect.” Drupal, Movable Type and others all have similar problems, but there’s a lot of people saying you should never Digg a Wordpress site because it will always crash. Wordpress needs a little tweaking, but for the most part, it’s the server configuration that is to blame. Maybe the new release of Wordpress will improve on some of the caching issues, but from what I can tell, it mostly improves on aspects of Wordpress that I don’t use anyway (draft saving, image handling, modules, etc.).

So, in my usual fashion, I’m doing my best to provide what I’m hoping will be useful information for anyone running Wordpress on a server they have some control over. The information in this post should help anybody running any kind of website on any LAMP server. It just happens to contain some Wordpress specific information as a bonus.

So go ahead, Digg this post to the front page. If my server crashes, I’ll bury my head in the sand and live in infamy while you travel on to the next most popular site on Digg. But I believe that the changes I’ve outlined here have significantly improved my chances of withstanding some serious traffic influxes.

Obviously, the easiest thing you can do is add RAM and a faster CPU to your server, given that it’s even an option. However, you can make any half-decent system run a lot better with a few tweaks.

Apache

There’s an excellent guide to Apache server optimization at HowToForge. You’ll need access to your httpd.conf file and the ability to restart your apache server (often ‘apachectl graceful’) to put the guide to use. Also keep in mind when reading it that the section on .htaccess files requires special attention if you’re using software that utilizes friendly URLs (and most does these days). If you don’t set AllowOverride to All, make sure that you include the directories that require .htaccess use in the directive.

MySQL Query Cache

Query Cache SettingsOne of the biggest and quickest performance gains I found was enabling MySQL’s Qcache. You can see the current state of your cache by typing “SHOW STATUS LIKE ‘Qcache%’;” (without the double quotes) at your mysql prompt. Both the query_cache_type and the query_cache_size need to be non-zero for the cache to be enabled. To enable your Query Cache, add to your /etc/my.cnf:

		query_cache_type = 1
		query_cache_size = 20M
		query_cache_limit = 2M

The size of the cache is determined by your setup, and the limit is determined by your caching needs. Here’s a passage from the mySQL newsletter:

Setting proper query_cache_size is the most complex task. It sets the amount of memory used for the query cache. One should find the right balance between the benefit you get from query cache and that non-cached queries slow down a bit, basicly due to less amount of memory available for other caches and buffers. Only benchmarking can point out the exactly best balance, but there are some guidelines, how to set this variable. Basic idea is that the more benefit query cache potentially gives you, the more memory it might be worth to allocate for it. Qcache_inserts will show you how many queries are added to query cache while qcache_hits will show you how many query results are taken directly from the query cache instead of executing them. You should compare qcache_hits value to total number of your select queries to see what is your current hit rate. You may increase or degrease query_cache_size to find the value, which provides best performance for you. Note that as the query cache content gets invalidated with update queries, amount of memory which query cache can use is not unbound. Qcache_free_memory shows amount of free memory in query cache, which is not used at the moment. If this value stays constantly high during the load it might be good idea to decrease the query cache size, i.e. to free some memory from the query cache to other caches and buffers.

From: MySQL AB :: Tuning MySQL Server 4.0 Query cache.

Other MySQL Tweaks

Key and Thread CacheThere are two other areas to be concerned about when tweaking, the Key cache and the Thread cache. Enter “SHOW STATUS LIKE ‘key%’;” at your mysql prompt to see what’s going on with your key cache. The ratio of actual reads to read requests should be in the 1:10 range. If you need to increase your key buffer, add: 

key_buffer=2M

to your my.cnf.

Enter “SHOW STATUS LIKE ‘thread%’;” at your mysql prompt to see your thread cache info.

Just like Apache, MySQL creates a new instance to process requests. On modern systems, it creates threads; on other systems it makes forks. Either way, it keeps some on standby, just like Apache. The way to tweak this is to see how many threads it’s making and up the cache until it’s making just a few. If you increase it too much it will never make a new thread, which means you’re wasting memory with unused threads. Cover the common case and then work on the fringes.

From: codepoetry - Optimizing a VPS for Getting Dugg

If your threads_created number is in the thousands, you’re hemorrhaging memory. Increase the thread_cache_size in your my.cnf to a number about twice the number of connected threads and work from there.

Also, If you’re having problems with “too many connections”, raise your max_connections in your my.cnf.

Keep in mind that each of these settings affects and is affected by the others. It’s a balancing act, and tweaking takes a lot of testing and time. I can’t give you a magic formula, but I can tell you that you need to keep in mind how much memory you have available and remember that most of these numbers tend to have a direct correlation to memory usage.

Optimize MySQL

Optimising MySQL database’s is a doddle if you have access to PHPMyAdmin (it’s a good idea to backup your databases before you do this!):

  • Click on the database your blog uses
  • Click the ‘check all’ box at the bottom to select all tables
  • Then click on the ‘Optimize table’ option in the drop-down box also at the bottom

From: Guide To Optimizing WordPress Servers » Connected Internet

Worpdress Specifics

WP-Cache2 ScreenshotWP-Cache2 is probably the most commonly prescribed cure for high-traffic blues. It’s an ingenious little system that does a better job of caching pages than Wordpress by itself can do. Be sure to turn off gzip compression if you use it. However, there’s more.

APC is a free PHP cache that can provide (allegedly) up to a 50% speed increase on your server. It’s actually not Wordpress specific, any PHP based site could get a boost out of it. The biggest downside is that you have to restart the server every time you change a PHP page. If you’ve finished working on your site for a while and are ready to let it run, APC might be a great choice. If you want to run it along side of WP-Cache, you’ll need to take a look at & APC « Mark on WordPress" >this article.

There’s a little-known plugin available called the Post Query Accelerator, as referenced here. In the words of the author:

The problem here is that the main post query uses ” AND post_date_gmt <= ‘$now’ ” … and $now changes on each load. qcache requires the query to be identical for it to be served from the query cache. And then I though… WHY does $now need to reflect the current time? The reason that $now is there is to prevent future posts from appearing, so why not just make that date reflect the date/ time of the most recently published post?

From: [wp-hackers] Freezing $now to increase query cache benefit

And that’s what the plugin does, it freezes $now and significantly reduces the time for queries. Try it, it worked wonders for me.

Addendum: As pointed out a couple of times now, the new version of Wordpress (2.1) now has this functionality built in. Thanks to everyone for keeping me on my toes.

Testing Under Pressure

I honestly don’t know for sure how to simulate the extended onslaught of a front-page Digg for testing purposes. I know there are ways, so if someone wants to enlighten me, feel free. In the meantime, a good testing method that gives you some feedback is to use:

ab -n 100 http://your.server/

at your terminal prompt, replacing 100 with whatever number of simultaneous hits you want to test for. While the test is running, have your web browser open and load a few pages to test responsiveness.

Go Forth and Multiply

If you have the power to tweak your server, hopefully this information will serve as a jumping point. I suppose it’s as important that we all write good content, but when we do, we should be prepared to handle the traffic that it can bring. So what do you say we get our servers whipped into shape and prove all those Digg naysayers wrong.

  2. Donncha O Caoimh 01.23.07 / 8am

    Upgrading to 2.1 will have the same benefit you get from the freeze time plugin mentioned above. You’ll see a dramatic use of the query cache!

    PS. your anti-spam measures aren’t working. This is my 3rd time typing this.

  3. Brett Terpstra 01.23.07 / 8am

    Thanks for the tip, I’m testing 2.1 on a local server right now and plan to make the switch over the weekend.

    I just disabled the current anti-spam feature, I’m not sure what it’s conflicting with but I’m having quite a few problems with plugins and wp-cache. Any suggestions for the best anti-spam measures? Bad Behaviour isn’t working with my new configuration, and I’m having a hell of a time with some of the other workarounds.

    Also, does anybody know of a way to get Landing Sites to work with wp-cache? I don’t really want to manually include all of the plugin code and rewrite all of the database access functions manually…

  4. Donncha O Caoimh 01.23.07 / 8am

    I’d recommend Akismet, but then I would wouldn’t I? ;) It works very well. It does let through a couple of spams occasionally when it hiccups, but it doesn’t happen very often.

    Landing Sites - you could probably add the http_referer to the cache key? Or at least do the same checks Landing Sites does and add a string from the referer in the key.

  5. brett 01.23.07 / 8am

    Alright, I’ve enabled Akismet, we’ll see how it goes ;-).

    I’ll keep playing with Landing Sites. Seems like it would make a good addition to this post if I can get it working…

    Saying anything is (Insert Verb) Proof is a huge leap of faith. See “Titanic”, “Hindinburg”….. for more info.

  9. brett 01.23.07 / 2pm

    Agreed. I just needed something catchier than “More-or-Less Digg Resistant”. You’ll note I make no claims of absolute invincibility in the post, or guarantees of the same for my readers ;-).

  11. Dougal Campbell 01.23.07 / 4pm

    Thanks for the tips. I was able to cut my mysql memory usage in half, which in turn gave me some more confidence to bump up my apache maxclients and maxrequestsperchild settings.

    I’m still scratching my head over the key cache, though. My read:request ratio is more like 1:550.

  12. Mao-B 01.23.07 / 4pm

  20. moeffju 01.24.07 / 7am

    Just a minor correction/addition:

    The query-cache-* variables use underscores instead of dashes.

    Also, what Post Query Accelerator does is now included in the WP 2.1 mainline code.

  21. Brett Terpstra 01.24.07 / 7am

    You are correct about the underscores, although it works both ways. I’ll edit the post, though, to avoid confusion. I found it both ways in various tutorials.

    And yeah, I read that about 2.1 yesterday. I’m currently getting my plugins straightened out with 2.1 and PHP5 on a local server, which doesn’t give me much of a chance to battle test the actual speed of the database under load, so I’m looking forward to seeing it work!

    Simple rules:

    1. MySQL query cache

    2. Use mod_deflate and mod_expires module on Apache

    3. Use eAccelerator (works without problems for PHP caching, and is much faster and more stable than APC kind of drivel) and Zend Optimiser

    4. Finally, use WP-Super-Cache, which includes WP-Cache but more than that. Read up on their site and it’s fairly self evident which one you should use.
