 * Hi,
 * Everyday when the traffic increases (around 6pm and 11pm) I start receiving several
   alerts from my PHP Application on New Relic of low apdex score, high throughput
   despite server CPU and memory are normal.
 * Here you can see the stats from the last 24 hours [https://db.tt/dYHpYNc3](https://db.tt/dYHpYNc3)
 * Is it possible that this problem is somehow related to your plugin?
 * Thanks

 * Very unlikely.
 * Are you using caching?

 * What is the difference when you disable Ad inserter?

 * Ad inserter is called only when WP needs to create a page. If cached page is 
   served, Ad inserter is not called.

 * Hi,
 * I’ve isolated the problem and Ad Inserter is in fact causing CPU spikes in my
   server when the traffic increases.
 * I don’t know if W3 Total Cache is handling correctly this problem.
 * Can you help?

 * I’ll be happy to help.
 * Are you using the latest version of the plugin 1.5.5?
    There were some changes
   since the last version.
