If you’ve experimented with social traffic strategies, you might’ve encountered the Digg Effect (or also known as the Slashdot effect) where a torrent of traffic (upwards of 1,000 unique visitors a second) brings your webhost to a screaming halt.
Matt Coddington over at NetBusinessBlog is masterful at this technique.
Observe his traffic:
One of his Dugg posts is: Building a Niche Minisite (Part 1)
One of the reason why your webhost might crash is due to the processing required in compiling the PHP code and serving up the page for each visitor.
This could literally kill the server resources during peak periods.
So Ricardo Galli’s WP Cache provides a workaround, by caching your blog posts as static pages, enabling you to serve hundreds of times more pages per second.
In fact, the plugin serves to “reduce the response time from several tenths of seconds to less than a millisecond.”
The plugin is WordPress 2.1.x compliant and pages have been whizzing during peak periods.
There’s a toggle to determine the cache expiry period, so you’ll want to adjust it, so you continue to serve up pages quickly and yet display updated content, like comments. (Else the new comments will not display till the expiry of the cached page).
To download, get it from: WP-Cache plugin.
