stripping the boot process down to the bare minimum makes it easier to identify the remaining time and determine whether it can be optimized further. + +With some experimental patches to both FreeBSD and Firecracker, it is now possible to boot a FreeBSD kernel in under 20 ms. + +Some of the recent improvements were discussed in Colin's recent BSDCan talk. + +This work is supported by Colin's FreeBSD/EC2 Patreon. + +Sponsor: https://www.patreon.com/cperciva
