After starting the broadcast: "Keep in mind that it'll take about 15 seconds to warm up"

What does that mean? What needs to warm up?

Boot up. It runs a full Linux stack, and the raspi CPU is not astonishingly fast.

I just rebooted my rapberripi running archlinux, It took ~2 seconds from the time I rebooted it to me being able to ssh into it.

The pi started to respond to ICMP packets in 19 seconds

Hmm, maybe a Raspberry PI could be easier and more reliable replacement to virtual machines?

(I love Vagrant/Virtualbox but sometimes, after putting the laptop to sleep, it stops working and I have to reboot).

They're not that fast. A single thread build of my python/c project (pillow) takes ~ 15 seconds on a vm, ~ 30 on an ancient core duo laptop, and ... still waiting on the raspberry. edit: 5:15. So 25 times slower.

I did an analysis of Mathematica benchmarks on the Raspberry Pi and found it to be 15x slower at best and much slower when there are CPU specific optimizations:
