Everyone wants their blog to be popular. Really popular.
The first problem is of course to become really popular. It’s not an easy thing to do.
The second problem comes in if you become too popular. Showing all those blog posts will soon bring your web server to its knees.
But fear not, dear WordPress blogger, there is a simple five-minute solution to this. And best of all, it’s free!
This blog has been on the front page of Digg and other social media sites several times, and as a result received some serious peaks in traffic. Still, we didn’t have any issues. How come?
Cache, cache, cache!
The single largest performance bottleneck of a WordPress blog is the MySQL database access that takes place behind the scenes. The key to a blog that can handle anything you throw at it, including being on the front page of Digg or Slashdot, is page caching.
Fortunately for you, others before you have thought of this and have made it easy to add page caching to WordPress. This eliminates 99% of the calls to the MySQL, and really speeds up your blog.
Caching with WP-Cache
We use a WP plugin called WP-Cache. Since it’s saved our bacon quite a few times, we thought it was only fair that we mentioned it.
Just follow the instructions on the WP-Cache homepage. You will be up and running in no time.
That’s it. You’re set, and ready for the front page of Digg. Good luck!
