Slow performance of Pro site

We are about to launch a new version of our website that has been designed completely using Pro. We are discovering that the performance of the site is very poor. For instance, the home page takes 10 seconds to load and the Google Pagespeed score is in the 20s!

We have tried most of the performance optimization techniques, including:

  1. Compression of all images
  2. W3 Cache plugin activation
  3. Removal of plugins that we could identify as performance bottlenecks

At this stage, we are out of ideas and suspect that perhaps we have some incorrect Pro configuration or setting that is the root cause. I have created a very simple “Hello world” test page. The information for it is in the secure note. I will really appreciate if you can analyze the page through Google pagespeed or similar tool and let us know if you discover something obvious. Much appreciated!

Hi Misha,

Thanks for writing in! I have checked your referenced URL, but I’m getting a blank page there. Upon further testing, it seems that you’re getting an error 500 on that page.

To investigate this issue, you can enable WP_DEBUG mode on WordPress and re-visit your page to see PHP errors related to the issue (https://codex.wordpress.org/WP_DEBUG).

With regard to optimizations, please try following our knowledge base article on how to increase your site performance and implement it accordingly (https://theme.co/apex/forum/t/customizations-performance/210).

Hope that helps.

@mldarshana, thanks for your reply. Please see my comments in the Secure Note below.

Hello Misha,

I am another staff checking in.
I am still seeing an error 500.

Usually an error 500 means that there is a fatal error. It could be a broken code or a PHP memory limit exhaustion. Could you please enable the Debug mode? You can do this by opening wp-config.php and adding

define('WP_DEBUG', true);

/* That's all, stop editing! Happy blogging. */

When you revisit the page, you should have some error output describing the issue in more detail. Meanwhile, ​we recommend that you increase your memory allocated to PHP. To increase it, please edit your wp-config.php file and insert these lines:

define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

You can add it before the line
/*That's all, stop editing! Happy Blogging. */

We would loved to know if this has work for you. Thank you.

@RueNel,

Thanks for the follow up. Yes, I think there was a configuration issue. It should be fixed now. Can you check again? Sorry for all this trouble. Would really appreciate any guidance here.

Hello Misha,

Your homepage loads at least 3.32s with a page size of 1.8MB which has 70 server requests.
I have check it here: https://tools.pingdom.com/#5a23140609400000

Please apply some measures like caching, js/css minifying, etc to increase your sites performance. We have discussed it in details here: https://theme.co/apex/forum/t/customizations-performance/210

We would loved to know if this has work for you. Thank you.
