Cloud metabase speed increase

How can i make my cloud metabase app faster. ??
i know about db indexes column .
what default config of system is used by metabase cpu , ram, threads etc??
and if there are multiple users using it same time. i want to increase speed for alteast "filter" functionality??

Thanks !

do you want to make your queries faster? can you please give a bit more context?

Queries are already faster. I want to improve filter dropdown.
unique values more than 300. so a search box is coming. so when typing it takes huge 20 seconds to lead result. i want to make that fast.
