To improve the performance of your e107 website, you can make the following changes:

• Enable caching for your e107. You do this from the Admin area > Settings > Cache. Once there, you should check Cache data saved to disk file and click Set cache status to save the change.
• Keep the number of active plugins as low as possible. Use only the plugins you really need.
• Optimize your e107 database
• Decrease the number of external and internal links on your pages. Leave only the most important ones.
