I have got a problem with Buddypress plugin. After I click on some group, there is a very late response. I need to wait even 10 seconds before it opens. I have noticed that after switching off social counter plugin, the groups open faster. I would like to use both plugins. My site: https://mojejaslo.pl/ .
Maybe the problem is with the social counter only, but that would mean that all pages or posts where it is placed would load slower. But you say it happens only in buddypress related pages so it is unusual.
You could contact the hosting provider and ask them to check error logs or maybe they have some idea why the admin ajax is so slow. Worth a try.
They blame the wrongly optimized page, which is not true, the page has 94 points in the pingdom test and the home page opens below 1.5 seconds. I received information that the admin-ajax.php processes and the index.php file are to blame. Sometimes it happens that the groups open very quickly, but after a few hours the problem comes back. I am asking for a suggestion and, above all, thank you for your help so far.
That is quite an unusual issue you are having. For me when testing your website, the buddypress pages load with an average of 6 to 8 seconds.
The social counter plugin will try and refresh the data every 3 hours, it will not make any requests consistently.
But why exactly would this plugin cause such problems for buddypress pages is very unusual. I did not see this before. Maybe the hosting could look into it more, investigate some more.
