Hi @alihmd94
the site is not slow just the add-to-cart ajax that taking some time to finish, and also the deleting from the mini cart also takes a little bit of time
Thanks for letting us know.
You’d first want to rule out the possibility of issues related to your (1) network connectivity speed and (2) insufficient server resources.
You can also try using the WooCommerce Speed Drain Repair plugin which would stops loading the extra items you do not need inside WooCommerce and speed up WordPress core admin-ajax.php file.
If the problem persists, in order for us to get a better idea of your setup, please share a copy of your site’s System Status. You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.
