Perhaps someone from the community has encountered and resolved this.
I have a fresh WordPress instance running on top of Plesk (standard setup: PHP 7.4, Nginx proxying Apache).
I have kept the site very light in terms of plugins however as soon as I activate Gravity Forms (and a few associated addons), the wp-admin load time spikes!
Without GF, wp-admin loads in <1s
Once Gravity Forms 126.96.36.199 is activated, this increases load time by an average of 7s
Once Gravity Forms Coupons 2.10.1 is activated, this increase the load by another average of 7s
Once Gravity Forms Paypal 3.3 is activated, this increase the load by another average of 6s
Once Gravity Forms Stripe 3.7 is activated, this increase the load by another 6-10s
So in total once these 4 plugins are activated, each page load takes almost 30s, sometimes even longer, which is insane and making me want to pull my hair out. I have other plugins like Elementor/Astra and their impact on load is negligible. And yes, I have tested with just GF plugins (without all the other plugins) and the impact is the same.
The weird thing I have noticed is that as soon as the Gravity Forms Stripe addon is activated, in my Apache access logs I start to see
POST /wp-admin/admin-ajax.php HTTP/1.0
I’m not blaming this on GF of course, if it was an issue with GF then we’d have 1000s of people complaining. I’d just like to know if anyone else has encountered and resolved such a conundrum.
