Hello and thank you all for trying to help me! :)

@User_9YNXK - Daniel, it would be great if you update your profile with your name/org, etc., so we can get to know you in the community.

I already save my display name like above but it keeps displaying 'User_NYNXK'.

I will share with you a image to have a idea of the look of the first canvas(it's in french). So we have 5 viz with 'Use a filter' enabled. I can start to filter on a Pie viz first, not the Map, but nothing changes, i have the same filtering time(~30sec) when all the 8 canvases are present. Keeping only this first canvas, results a filter time much smaller (~2sec)

Behind the scene when I click for exemple on a map departement i have 18 very fast queries(Execute time ~0.5 - 0.7 seconds in Developer mode). I know that Bi Server execute all this queries in parallel (that explain having globally 2 seconds when I apply the filter and I keep only this canvas.

With red arrows I indicate the 5 viz with 'Use a filter' enabled and in orange the number indicating the corresponding viz for the 18 queries(tiles, pies and maps)

I appreciate any constructive comment!
