First tests are very promising and motivate for harder work. </p> <p>What has it started from? I've been working with my friend on a quite popular sport blog. I'm using <a hreflang="pl" href="http://wordpress.org">Wordpress</a>, which doesn't require too much care, is flexible etc. Unfortunately Wordpress with a few plugins can perform even 100 database queries - it can blow every server. There is, however, a blog engine which generates HTML files by default (<a hreflang="pl" href="http://www.movabletype.org/">MovableType</a>) but when you have got a blog with hundreds of posts, even a small change can require to generate all the HTML files again... </p> <p>Of course, there are caching plugins for Wordpress, such as: <a hreflang="pl" href="http://blog.invenzzia.org/en/post/WP-Cache">WP-Cache</a> and <a hreflang="pl" href="http://wordpress.org/extend/plugins/wp-super-cache/">WP-SuperCache</a> but from my own experience I know that they are not able to deal with bigger traffic. They generate a lot of PHP files and cleaning them can consume many server resources. WP-Cache can even slow down your Wordpress!</p> <p>WP-SuperCache is a bit better than mentioned earlier WP-Cache, because it generates HTML files for unlogged users, but problems from WP-Cache still remain.</p> <p>So why wp-htmlcache is so special? The mechanism generates static HTML files that are served to all the users. It doesn't matter, if they've already posted comments on your blog or not. Through that simple solution our blog can deal with huge traffic (Digg effect won't be a problem anymore!).</p> <p>Can we see any results? The answer is very simple ... just look below:</p> <pre><code>Before installing wp-htmlCache<br />Process CPU seconds user machine count average<br />php5.cgi 12986.3400 99.997% 54.110% 60549 0.214<br /><br />After installing wp-htmlCache<br />Process CPU seconds user machine count average<br />php5.cgi 5144.7600 99.880% 21.437% 24263 0.212<br /></code></pre><p>As you can see, the server usage decreased by 50%! It's obvious that blog readers feel the difference, too. Every page loads faster than ever.</p> I'm currently testing it and removing all kinds of errors and bugs, but wp-htmlCache already relieves the server in a significant way. Soon our Wordpress plugin will see the daylight ;-).
