Hello Kelly,
Thanks for going Pro and welcome to the forums!
And thank you for getting in touch with us regarding this topic. Sorry you are having this speed issue.
Just want to make sure, did you try to do a conflict test before to see if maybe another plugin or the theme is influencing the load times?
Also, if you are working with a large number of events that can influence load times of some views, esp. the month view. In this case using caching for month view and disabling JSON LD can be of some benefit.
I also recommend the following article for further information: https://theeventscalendar.com/knowledgebase/performance-considerations/
Let me know if I can be of any assistance. In this case, please also share with me your system information and a link to your site so I can check.
Thanks and cheers,
Andras
