Graph Api calendar events performance is very slow

Nirenjana Raghupathy 21

I’m using the below calendar API to get calendar events for a given user
GET /me/calendar/events

However I notice that by default only 10 records are returned. I’m trying to include top parameter in the url and do a callback in case nextlink has a value in the response.

I’m trying to add $top=500 to the api url. And I noticed that when top parameter is included, time taken for the response to be returned is very high. It does not matter if I use top=50 or top=500.

Without the top parameter, the response is returned in lesser than a second.

Any idea on how I can bring down the performance in this scenario?

Have you tried using Graph Explorer and seen the same behavior? I do not see a similar behavior.

Also please provide the details of the SDK you are using.

Hi Danstan,

Thanks for your reply.
Below is a screenshot of what I am trying to do:

The response is taking about 14 seconds.
And the total no of events, I have is about 330.

Would you mind sharing the URL that you are using?

Thanks,
Nirenjana

Hi Microsoft,

I am facing the same issue. As soon as we add top in the API the performance is very low.

Thanks,
