What is the best way to disable the mitigations if you don't care about security but care about performance?

You can set kernel boot parameters to disable the mitigations on a patched kernel.

Don't update your OS/Microcode.

Sounds like a good way to remain insecure to all other types of vulnerabilities.

It is, but if you care only about performance, and not security, you don't care.

Let me rephrase: Sounds like a good way to remain insecure to all other types of vulnerabilities, and to never receive any performance improvements.
