Interesting; I often wonder how my single do-everything hub's stats compare to mulit-hub setups.
My C-3 (81 Zigbee+Z-Wave devices, WebCore; still on 220.127.116.11) after approx. 75% of that uptime. It's obviously busier; still runs the lot flawlessly with 3-4 days of snappy performance until its memory declines and it needs rebooting):
Edit: apologies for the eye chart imbeds...
Local apps show 1h 28m 17s busy
