You may find that you no longer have need for a plugin or that you have to remove some plugins from your WordPress installation. Too many plugins can drain system resources and make WordPress very slow. The number of plugins you can install and activate before you see performance problems depends on the server you are using or your hosting provider.
When you need to uninstall a plugin, the process is just as painless as installing a plugin. Like installing a plugin, you can uninstall a plugin automatically via the Dashboard or manually.
To uninstall a plugin using the WordPress Dashboard, follow these steps:
Make sure that you have deactivated the plugin before proceeding.
The Delete link appears beneath the name of your plugin, as shown in Figure 2-15.
The Delete Plugin page appears, asking you to confirm whether you want to delete the plugin, as shown in Figure 2-16.
