admin-ajax.php slowing page loading

Yes, the page it is slow loading.

I like this service for investigating load speed problems:
https://tools.pingdom.com/fpt/

Its showing that there is a big wait for the first file, ie, before WooCommerce kicks in.

(It does take a long time for admin-ajax.php to load, but it looks like that’s happening asynchronously, so its not delaying other things.)

So I ran the ping test and that was giving an average round trip time of 88 ms, which is quite long. You may get different times depending on transient internet conditions. My own site on cheap shared hosting gives a 16 ms ping time.

Next we want to know how many other sites are hosted on your webserver, and this service:
https://www.yougetsignal.com/tools/web-sites-on-web-server/
says there are over 1000 other sites. This is a large number, I would expect to see say 200 – 500. It looks like your host is piling on sites on one shared webserver, so its slowing down. I suggest you put in a call to your host tech support. Ask them to transfer your account to another of their webservers which has a better spec and/or less load. If you don’t get satisfaction, consider moving hosts.

You might consider trying a cache plugin, such as WP Super Cache or WP Total cache. Of course this won’t help the first page load, but it may help some of them.

Great reply lorro Thanks , contacted the host and they admitted a problem at their end. I’ve been using pingdom but your suggestion to check yougetsignal to see how many sites they are running per server was priceless. I checked the other sites I have with the same host and they are all running 1000 on a server. Guess that’s what you get when you sign-up for a cheap deal. I do have caching but I’ve deactivated it to see load times without it activated. Thanks agin
