Is this slow page generation time?

    I have been trying to diagnose why TTFB is on average about 1.3 seconds (and the rest of the load time is about 200ms – so my website is waiting about 80% of the time). Using your plugin I can see Page generation time is .9699 seconds (3.2% of 30s limit). Peak memory usage is 18KB of 132KB limit. Database query time is .056 seconds and there are 133 database queries.

    So, is about one second of page generation time normal (which would be contributing to the TTFB)?

    I use Flywheel hosting which is a WordPress Managed Hosting company.

    Thanks.

    0.9 seconds of page generation time is pretty high. That’s a lot of time for PHP to spend generating a page. A well-performing site should generate the page in about 0.1-0.2 seconds, but that’s also very dependent on how good your host is (ie. how fast the storage and memory are).

    I would take a look at the HTTP Requests panel and make sure there aren’t any HTTP requests happening on every page load. The P3 Profiler plugin can help you identify if a particular plugin is slowing your site down. Beyond that, my next step would usually be to install XHProf, but that’s probably not an option on a shared or managed host.

    John,

    First thank you very much for your prompt response; I also have rated your wonderful product a 5.

    My host – Flywheel Managed Hosting – is supposed to be one of the best out there (https://reviewsignal.com/blog/2014/11/03/wordpress-hosting-performance-benchmarks-november-2014/).

    There are no HTTP Requests happening on every page load. I emailed Flywheel hosting support (see below) but they were no help.

    I ran some tests. With Genesis’ stock theme, no plugins (except for Query Monitor) and no extra code, page generation time was .2 seconds. With my Dynamik theme (and no plugins or code) it jumped to .48 seconds. It then jumped to .9 seconds when the plugins and code were added back in (only .05 seconds less .85 seconds without the code).

    TTFB has been ~1.2 seconds without CloudFlare and a little more once CloudFlare is hooked up. I optimized it some more (loading FontAwesome and Google Fonts asynchronously) so it has a 94 performance grade. Now TTFB is about .9 seconds with total load about 1.22 seconds (https://tools.pingdom.com/fpt/#!/dURdaQ/https://www.mbaprepadvantage.com). I cleaned out the cache about an hour ago so it is a little slower now.

    Thanks.

    Flywheel Response

    Flywheel first responded that I am over my traffic limit with 500 page views a day so Flywheel stated I would have to upgrade before they were willing to investigate it.

    Flywheel mentioned that I am running a high amount of plugins. “That being said, if it’s crucial for you to optimize the performance down to this level, with a shifiting landscape of plugins/themes/features/etc, we would highly recommend you move to a VPS that you can manage on your own. We’ve built Flywheel to make the majority of WordPress sites perform very well – and while we’d like to make that possible down to millisecond improvements in every case, it’s not often a feasible task for our modestly-sized engineering team, or for our customers, who then have to allow for time for our engineers to investigate these issues.”

    I also tried P3 Profiler but it did not work. It shows only P3 Profiler plugin using resources which has been recently a common problem for the plugin.

    Thanks for the suggestion on XHProf, but it is a managed host.
