Hello Steven, 

Thank you for purchasing Amelia, and for reaching out to us.

The slow load can be caused by a lot of things - the number of appointments you have, the number of customers, the number of employees, etc.

Other than Amelia, it could be caused by the amount of other data you have on the page. 

Are you on a dedicated, or on a shared hosting? 

Can you increase the php_memory_limit on your site?  If you're not sure how to do that, you can reach out to your hosting provider. 

Please check out our demo sites (link) and see how the plugin should behave on a site with dedicated hosting and good server performance.

Hello Steven, 

That should be enough but like we mentioned it can be caused by u number of things the number of appointments you have, the number of customers, the number of employees, etc. 

Amelia itself is very fast but if you have her to pull data for let say 5000 appointment, then of course it will take her some time.

We've had customers that used Amelia for Covid-19 vaccinations, and they worked with around 1.000 appointments per day. When you have a lot of data (services, employees, appointments, and most likely customers) combined, so if the form is not filtered (like [ameliabooking service=1] or something similar), the form loads all services and all employees. 

If you're connected to Google and/or Outlook Calendar, those are checked for availability as well. Once the service is selected, the employees are drawn and their free time slots are displayed. So, there are a few calls that pull relevant data, but that shouldn't be causing a lot of issues.

Maybe you can try increasing the timeout limit as well. Also, have you tried enabling the "Load Entities on page load" slider in Amelia Settings/Activation? That should avoid AJAX calls
for fetching entities (services, employees, locations, packages, tags) and should increase the performance.

Let me know if that helped.
