System performance for notifications

When the system has a large amount of data, I found the interface of notification part is very slow, which needs to be loaded for a long time. What may be the cause?

interface: ‘NotificationsDisplayerUIX?outputSyntax=plain&action=getUnreadCount’,

Hi, what version of XWiki are you on?

Could you give us some estimate of how large this is?

Thanks

Okay,
xwiki:10.4,
and then I use the Postman to test the interface, I found that it took long time to load data when a user first logs in.

The number of data is about 30

and the params are as follows:

We’ve improved a lot the performance of the Notifications system in more recent versions. You should upgrade at least to 10.11.3.

I don’t understand what you mean here and the screenshot doesn’t look like XWiki.

emmm…
I tested the interface separately.
okay,I try to upgrade the version.
Thanks.
