Power BI Cache

Thanks v-yuta-msft, for your reply.

I am not mentioning about cache refresh.

I am tring to understand cache retainment for reports.

So the scenarion is this:

Suppose I would like to share a PBI report with one page only with my users . Please note I am sharing report not dashboard with tiles.

First time the user opens the report its takes 10 secs to fully load.

Is it possible that the next time the user opens (within 15 mins) the report will take <10 secs ? 

This will only be possible if the report has stored cache for the first time load.

Also if another user changes the filter selection from A to B suppose, will the cache be stored i this case too?
