Very slow theme, performance server?

Hello, I am checking with the Query Monitor plugin
before theme installation I was at 0.32s,
After installing the theme the site is very very very slow, I am at 4.42s
I did a clean install before installing the theme
Is there an adjustment to be made?
Server level of adjustments required?

Is it possible to deactivate 100% team-wars?

Thank you 🙂

Intel Xeon E5-2630v4 6 Core
16 Go DDR4
