99% of containers don't leverage OS instrumentation or really anything unique from the underlying platform. It's typically just run this Java/Python app and maybe run this database or infrastructure component.

And there is nothing inherently inefficient about the Linux kernel. It's more that once you pack on all of the userland components you do end up with a sizeable attack vector.

The first thing that comes to my mind is the user space networking drivers for linux [1]. They aren't very ergonomic, but the massive speed increase that is possible shows how inefficient normal linux networking is.

The promise of unikernels is the speed of user space networking but with good ergonomics.

Like I said earlier, if I had to bet, I'd bet on Linux.

But there is work to be done.

As much as I like dpdk, XDP and eBPF can potentially hit the same rates as dpdk. But we're currently in a state where more driver support is needed.
