Optimizing dashboard and queries

$

Hi forum,

I have a functionning dashboard in cde but i have a few problems...
I have 8 "filters" (lists which give me some options to filter my queries) and 7 graphics so in the end 15 queries : yeah that's a lot.
Having all of those things on my dashboard gives me an issue : it's super slow...
So i'm asking how i can optimize my queries/components ? (Just general things)
Also, i have to add that pentaho seems to refresh the components (listening to a filter) before the filter refreshes the query get refreshed... and reutrns a wrong result.
For that i added some javascript code to manually refresh the components right after they got refreshed (Post Fetch part) : without that, it's a bit faster of course but it's also wrong...
Maybe i did something bad in my queries or anything else ?

Thank you in advance for your answers !
