Graph API calendar getschedule response time is slow.

Our application uses this API to retrieve the available time of more than 20 meeting rooms.

What we want to do :
I want to get a list of available meeting rooms at a specified time.

However, in some cases, it may take more than 20 seconds to get a response if there are many meeting rooms.
I have not found a way to achieve this other than using this API, but if there is a better way, please let me know.
