Amazing performance improvement!

Install is not like other plugins — and in fact if you do upload it to plugins and then activate it, it’ll bring your site down in many cases.

You can upload it (but don’t activate!) and then use the server side to move the plugin file manually into wp-content (and then delete the uploaded plugin folder and readme.txt).

But that’s not enough to make the whole thing work!

You also need memcached running on your server and properly configured, and the pecl memcache extension compiled on the server side in your php configuration, too.

Make sure to use a unique salt as well.

Once it’s all there, the speed improvement is significant!

Happy to try and help those that respond to this thread if you need — or at least try to get you pointed in the right direction.

Thanks for the plugin, devs! Appreciate as you update and keep current as well!
