When you set up a new blog using WordPress you probably do not think you will get a lot of traffic, especially at first. However, of course it is a goal for any site to continually gain popularity and thus obtain more traffic. But, what happens when your site gets a lot of attention and suddenly becomes a high traffic site? Will using WordPress hinder the availability of posts on the site? Will it be able to handle the sheer volume of traffic that may occur once your site becomes extremely popular?

WordPress is designed to handle high traffic. However, as with any site and any software program it is important to optimize your site for maximum efficiency. The more people you have browsing your site, the more you want your site to load quickly so you can expose your posts the most possible viewers. WordPress itself will not be a hindrance to a high traffic blog. However, there may be some issues that will slow your site or make it unavailable.

If you have a web host or if you run a private server to host your site, make sure it is able to handle high traffic. If your site continually gets hit and the server is not able to handle the capacity you may need to be moved to a lower populated server, a dedicated server or move to a network that is better equipped to handle high server loads.

If you have optimized your network and server capacities to handle high traffic and still see some issues, you may want to make a few adjustments to your site to further optimize it for high traffic blogs. The WP-Cache and WP-Super Cache plugins available through WordPress can assist you in loading your pages quickly. If you have a lot of extra bells and whistles on your site you may want to consider simplifying it. Using fewer graphics is one way to get pages to load quicker. You should also only use the necessary plugins to make your pages run efficiently. If you have a lot of extra plugins that are not necessary, remove them so they are not called when the page is loaded.

WordPress is designed to handle heavy traffic blogs. However, the WordPress software is not the only consideration. You need to make sure your site is optimized to load as quickly as possible by reducing or eliminating unnecessary graphics and plugins. You should also use optimization tools available through WordPress. Ensure your web host and network can handle the traffic capacity you are experiencing or change providers. If you ensure all these steps are adhered to, your heavy traffic WordPress blog will work quickly and efficiently.

• There will not cache anything with “known” users. Users who are logged in, or comments. In general, a small minority of visitors to each site.
• Update the cache is very deficient. If you leave a comment, so the cache of this page may not be updated immediately. The cache lifetime is set to 30 seconds, and when you leave a note to a “known users” and see Uncached version of the page anyway.
• If items are updated in the cache is invalid.

If you do not know what memcached, or how to sign, then you certainly do not want to test them. If you do this, use Google, and about her. Unfortunately I have no time to explain how to install.
