Metabase slow

Good morning!
I have a problem with my Metabase Starter.
Some charts are showing this message below.

I had a crash in my database previously and after increasing the memory of it, began to load slowly.

Also, I try to do any queries in Metabase and it takes a long time to execute.

Can someone help me?

This usually takes about 0 seconds.
(That’s a little time-consuming for a Dashboard)
