 * Hi guys,
 * Im trying to figure out, first of all what exactly is the Profile overhead and
   why does it take half of the load time?
 * Total Load Time: 1.1963seconds avg.
    Site Load Time 0.6084seconds avg. Profile
   Overhead: 0.5879seconds avg. Plugin Load Time: 0.1534seconds avg. Theme Load 
   Time: 0.2604seconds avg. Core Load Time: 0.1809seconds avg. Margin of Error: 
   0.0137seconds avg. (1.1963 observed, 1.1827 expected) Visits: 19 Number of PHP
   ticks: 6,320 calls avg. Memory Usage: 27.91 MB avg. MySQL Queries: 127 queries
   avg.
 * Hope you can help.
 * Best Regards
    Rasmus

 * Hi Rasmus,
 * The load time spent profiling code. Because the profiler slows down your load
   time, it is important to know how much impact the profiler has. However, it doesn’t
   impact your site’s real-life load time.

 * Hi Kurt,
 * Im sorry, but I do not understand. When you are saying profiling code does that
   mean the time it takes to execute all of the code that is trickerd before the
   load time is complete?
 * My issues is that my ‘time to first bye’ is more then a second and that is not
   quite goode enoguh SEO wise.
 * Hope you can explain a bit more in depth.

 * Hi Rasmus,
 * When P3 measures your performance, this is called profiling. What it does is 
   track every function call that WordPress core, plugins, and your theme makes 
   and measures the time it took, and traces it back to the file it originated from.
   This measuring & tracing takes time. The overhead of measuring and tracing is
   called the “profiling overhead.” Say your site takes 1 second to load normally,
   when it’s actively profiling (or “scanning”) this time may go up to 2 seconds
   or 3 seconds. These numbers are just examples and they depend highly on your 
   server and website configuration.
 * So, in your numbers, your TTFB is represented by this number:
 * > Site Load Time 0.6084seconds avg.
 * And the reason the profiling overhead is so high is because you have a lot of
   function calls happening:
 * > Number of PHP ticks: 6,320 calls avg.
 * A tick is _like_ a function call or a WordPress hook, but that’s a **grossly**
   simplified explanation. You can just think of a tick as “a thing that happens
   that requires processor time.” Generally more ticks means more time. Again, that’s
   grossly simplified. Please don’t focus on optimizing that number too much, it
   just shows what P3 is monitoring that’s taking so long.
 * I would suggest doing a few things:
 *  * Doing a manual scan by clicking “manual scan” and using a second browser to
   surf your site (make sure you’re logged out in the second browser). Then click“
   finish scan” in the first browser. This will give you more accurate results for
   an anonymous user.
    * Try to lower the # of SQL queries. Use some of the other
   graphs to figure out what’s going on or toggle plugins on/off and repeat the 
   scan until you figure it out. * Try a caching plugin. P3 won’t work with caching
   plugins, but tools like webpagetest.org and tools.pingdom.com will give you a
   good load time score * Try looking for ways to lower your overall render time.
   Tools like webpagetest.org and tools.pingdom.com will give you hints if you have
   too many external scripts, or too many images, etc.
 * Hope this helps!
