I learned the hard way that CPU misses can add even 30% of request latency, especially when you often do I/O eg to external services like db/Redis/etc I didn't notice such behaviors on AWS. but when thinking about it, I read somewhere that one reason they have dedicated CPUs is for partitioning CPU cache so it's not shared between VMs. so maybe with some tricks they could get some free compute without side effects?
