How to disable spectre mitigations in Fly micro VM kernel?

#1

How would we be able to set “mitigations=off” in the built Fly VM kernel so that it runs with faster performance?

#2

This is not currently something we’re set up to let apps on Fly.io do. We’ll keep it in mind!

#3

If the host kernel is running with mitigations enabled, do the micro VMs even need to run with mitigations as well?

#4

Seems pretty similar to the question of whether a browser needs speculative execution mitigations. Again, a thing we’ll keep in mind moving forward.
