Worse performance compare to linux

[Softwafe Engineer]

Hello. I've noticed worse performance in graphical session in freebsd than
in linux.
I have thinkpad with intel graphics. I've installed drm-kmod and I suppose
it works correctly. Even with fixed cpu frequency in sysctl  to turboboost
performance is not good as linux by default. I've noticed freezes and
slowly.
I see it even in vim with syntax highlighting.

What do I do wrong?
