Excessive Admin Loading Time

**Dave224** · 10 Apr 2021, 02:16 PM

I'm experiencing excessive loading times for admin after entering credentials and clicking submit. Times of two to three minutes are common. Occurs on my development system and live test system. The main culprit appears to be gstatic.com which is loaded in index_dashboard.php and stats_sales_report_graphs.php. Is anyone else seeing this behavior?

Although not a major contributor to loading times, there are many javascript files loaded such as jquery-3.5.1.min.js, jquery-ui.min.js, jquery-ui-i18n.min.js, jAlert.min.js, jTimeout.min.js, and bootstrap.min.js. Are any of these redundant and could be eliminated?

That long load-time can be exacerbated if you have multiple plugins that are 'calling home' to see if there is a more recent version available
(think SiteMap XML, for instance).

Combined with the setting for My Store :: Show if version update available (which also performs that look-up), that can be quite the extension to the login time.

Here's another fix you can backport to your version:

Even though it is a neat addition, I find the admin dashboard (but not all admin pages) causes a lot of load lag.

One thing to test is if you remove most of the dashboard does the page load delay go away (just don't tell swguy I made that suggestion).

To test whether the issue is with certain dashboard contents, try changing admin/index_dashboard.php to just:

Code:
