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?

- sbierwagen 13y agoBoot up. It runs a full Linux stack, and the raspi CPU is not astonishingly fast.
- parimm 13y agoI 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 http://pastebin.com/JQmCmHXH http://pastebin.com/JQmCmHXH
- swah 13y agoHmm, 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).
- wiredfool 13y agoThey'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.
- Adrock 13y agoI 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: http://adereth.github.io/blog/2014/01/06/benchmarking-mathematica-on-the-raspberry-pi/ http://adereth.github.io/blog/2014/01/06/benchmarking-mathem...
