Database cache impact the Frontend?

[chaddyxx]

Hi,
How much Database cache is important for the optimization of the website?
If I use Full page cache, can I pass DB cache?

Regards.

There are some cases where some caches can cause performance issues in some situations.
Generally caching is a good thing.
Test performance without it. Turn it on, test performance, turn it off, test performance, etc. Pick the one that worked the best and run with it.
