Why does the Events Table update take so long?

When demonstrating the PI Vision 2017R2 Events table to a customer, it was hard to explain with the current update rate for the Events Table.

 

There is a nice Acknowledge button, but when we then go ahead and acknowledge the Event, it takes several minutes for the table to update and show the status as 'Acknowledged'. Why does this take so long?

One could think about performance reasons, but when i set the table filter to exclude acklowledged events, the update is immediate.

 

It is very difficult to build a proper user interaction with the current behaviour...
