Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. The latest AWS hypervisor, Nitro, uses everything to provide a new hardware-assisted hypervisor that is easy to use and has near bare-metal performance.

All I wanted was to record a forty-second voiceover for a throw-away video , so I fired up the Windows Voice Recorder app and hit the record button. A twenty-second delay for recording a forty-second clip is a pretty bad efficiency ratio. That said, this post describes one example of why modern software can be painfully slow.
