Servers sitting idle is a strange concept. Ideally those resources should be powered down and workloads should be consolidated until the machines reach an optimal level of utilization.

You can’t boot a full OS in seconds, but you can boot a thin hypervisor and have compute resources immediately available. Same applies for hard disk drivers that can be spun down or flash devices that can be unpowered when not in need.
Doubling PHP performance is huge.
Ideally Ubuntu would take these optimizations and incorporate them into their stack.
> Ubuntu still frustratingly defaults to schedutil or powersave governors even on servers... A rather silly default many will argue
The carbon footprint of servers sitting idle is important, too.

If you want readily available resources, you can't power down servers when they're not being utilized.
That's not to say you shouldn't make attempts to conserve power with better performance scheduling on the CPU.

Wouldn’t disagree, but have I got bad news for you.
Global utilisation rates are very low. 5~15%
I guess the reality is that solving that would require a practically impossible level of coordination across the industry.
