remove admin-ajax.php

If I understand you correctly, you want to disable WordPress from calling admin-ajax.php for all users because of performance concerns? Is that correct?

Instead of disabling a core WordPress file which is a *bad idea*, I would focus on other website performance optimizations like image and file sizes across the site, reduce the amount of 3rd-party scripts/code on the site (like social networking widgets) and I would also suggest taking a look at your server/hosting needs and optimize or upgrade there for better performance as well.

look at this report : https://gtmetrix.com/reports/upmusic.ir/rhHAUMIs

in the waterfall they dont have admin-ajax.php Request

and its for my site : https://gtmetrix.com/reports/pardismusic.me/KsyUiVoF

what i can to do for being faster ?

I have the same question. I use woocommerce plugin – which is great BUT you need the extra plugins to make it the consumer grade shopping cart the public expects. I recognize that these add to the wait times but this is intolerable. I worked at it for months and cannot seem to get past this issue.

Just trying to get to the cart is a 9 second wait on a fast server with caching and all the speed up gimmicks I could add. If I remove those things I can wait a minute or more for the same page. I have disabled all plugins and I still have this problem. go to this link https://gtmetrix.com/reports/www.open-mesh.ca/m5CMUNJZ to view the “Waterfall” tab and you will see just how crazy it is waiting for nothing at the beginning and everything else loading in a split second. I only have about 24 inventory items so it isn’t database size. It is hard to imagine WordPress continually ignoring this BIGGGG issue. I need a fix for this issue or I will have to move to Magento – I don’t want to but I might just have to.
