This chapter has touched on some ways to improve the performance of your WordPress MU and BuddyPress installation.
Specifically, we learned how to use caching to speed up the page loading times of our site and ensure that the site can cope with large amounts of traffic. We also talked about speeding up page load times and reducing bandwidth usage by streamlining our theme, hardcoding some things that were previously dynamically generated, and reducing the size of the images that make up our theme.
We touched on some server-side optimizations and talked about alternatives to Apache, which may be useful for bigger sites.
We learned how to troubleshoot slow loading times, how to determine where the bottleneck lies, and how to fix it.
We also discussed tweaking your server setup and testing your site's performance.
Now that we've learned about handling large amounts of traffic, we're ready to look at troubleshooting and maintaining your site.
