Should I migrate 19.1. to 22.1 performance wide?

[labsy]

Hi,

I have 19.1. on ESX 6.5 server and yes, it's working. A lot of rules, a lot of NAT translations, and a lot of blocklists (aliases, external lists). Cannot auto-upgrade to any newer version, dunno why, but it does not work.

I am thinking about manually rewriting all rules to 22.1 version.
What ya think - will there be any benefit performance-wise or security-wise?

Do you use bridges?
If so FreeBSD 13 has improvements there
