Hi, Diane.
Thanks for the detailed information.
Here are a few thoughts:
- I find it odd that MailPoet shows up in your P3 results when you have a notice above that says MailPoet is not active.
- I saw from your 2nd message that the two screenshots compare 8 active plugins to 13 active plugins. I would have expected to see only a 1-3 plugin difference (since you have TEC, PRO, and Filter Bar), not 5.
Anyway, we do have this KB article that may help: https://theeventscalendar.com/knowledgebase/performance-considerations/
In short, yes, PRO does take more site resources and a well-resourced site should be able to handle it just fine.
I’d also recommend your host have the recommended configurations from https://wordpress.org/about/requirements/
I hope this information helps.
Please let me know if you have any follow-up questions on this topic.
