When a website or application feels like its 'slow performing', the common assumption is that its a 'server issue', whereas in many cases the bottleneck in terms of performance can be within the application / script itself.
When a website does slow down, there can be issues within the code which traditionally have been difficult to diagnose. We are now proud to announce that we offer 'PHP X-Ray' to allow you to generate reports for your sites giving you a deep insight into performance-related issues.
PHP X-Ray, included with all of our Shared / Reseller and Premium Hosting plans, provides detailed information on performance bottlenecks within your PHP applications or WordPress installations. If a site has sluggish plugins, database queries, functions, or external calls, the X-Ray tool helps pinpoint the underlying problem.

Once you have visited the site a few times, you will see the 'Collected Requests' column will be populated. At this point, you can then view the results of the collection, which will allow you to diagnose which particular area of your application is underperforming.
For instance, you can see a list of traces on database queries:
