To many requests to the backend

[kulbabskyy]

Hello,

I've encountered an issue with my custom update script in a WordPress plugin when caching is disabled. The problem arises irrespective of which admin page is accessed, resulting in multiple unnecessary remote requests.

The relevant part of my __construct() function looks like this:

public function __construct() { $this->cache_allowed = true; }
Despite this setting, the update function $this->request() is being called multiple times (around 9 times) during a single admin page load. This behavior seems to occur on every admin page load, leading to a significant number of redundant requests to my backend.

I have calculated how the many times the function is called:
int(1) int(2) int(3) int(4) int(5) int(6) int(7) int(8) int(9)

This issue appears to be related to the number of plugins installed on the site (currently, I have only three plugins, including the one with this update functionality).

I am seeking advice or solutions to optimize the update check mechanism to prevent these excessive requests. Any insights or recommendations would be greatly appreciated.

Thank you!

We can minimize the issue running the offending code like this:

add_action( 'load-plugins.php', function() {
    add_filter( 'site_transient_update_plugins', [$this, 'update'] );
});

update

I didn't have the cache_allowed enabled, once I set it to true, the problem disappeared.
