Performance issues when switching from plugin to general tab

[rklec]

I've seen several performance issues pointed out, but my one is special:

STR

1. When loading the /admin/general tab, everything works flawlessly.
2. Then sswitch to /admin/plugins, i.e. the plugins tab.
3. And switch to /admin/general back.

What happens: It loads for a very long time and finally does a 504 Gateway Time-out of nginx

Reducing the numbeer of plugins seems to fix this,l but even with only q2apro/q2apro-warn-on-leave and NoahY/q2a-badges installed (both from GitHub), it cannot finish loading even after several seconds.

This is a dockerized test instance and no one else accesses it, so there should be plenty of hardware resources for performance.

v1.8.5
PHP 7.4.11
10.4.10-MariaDB-1:10.4.10+maria~bionic
nginx/1.18.0

Edit: The plugin options also load very long or timeout.

It may be due to the plugin update checks. If you have a lot of plugins it will fire off many AJAX requests to check for updates.

Try commenting out this line in admin-plugins.php and see if it solves the issue. If so, we are working on making this better for the next version.

Indeed thanks. Indeed the issue happens when your network connection is slow or no outgoing network requests happen.
Maybe set a timeout for network requests, so they can at least fail and not block the whole application. (curl CURLOPT_CONNECTTIMEOUT)

For me this issue is closed, so you may close it, if you want.
