How dataset runs in dashboard

sairag

I have created a dashboard. In which I have 10 datasets and one 4*4 grid in my design. In each block I have one report, which uses 8 datasets from the available 10 datasets. The rest of the 2 datasets I using as parameters.

My doubt is , when I run my report how / in which order dataset runs in dashboard?

- Is each block of the grid runs at a time ? If so is there anyway we can tune to run parellelly.

OR

- All the reports in dashboard starts to run at same time?

Thanks
