FreeBSD is most likely slower than linux in most scenarios. ZFS is supported natively in Linux ( Ubuntu ), jail are terrible compared to Docker, since Docker is very popular there are a millions tools built arround it, it's not just for sand boxing, it's a part of a complet development process.
Who cares about boot process on a server seriously?
"FreeBSD's network stack is (still) superior to Linux's - and, often, so is its performance."
This is wrong, if it was the case most large compagnies would use BSD, atm they all use Linux, the only large compagny using BSD is Netflix because they added some tls offloading in kernel for their CDN which could have been done in Linux btw.
imo don't use tech that is not widely used, you're going to reinvent the wheele in a worse way because tool a.b.c is missing.
