NXT started with java -Xmx150m ... (This RasPI is a model B with emulated ram (gpu_mem=260) for model A, model A is arriving this week)

Unlocking an account with some transaction takes a while. After some unlocking attempts it opens successfully.

Scanning blockchain takes ~9 minutes. 2MB's swaped.

PS: SolarPasPI (model B) was running 46 hours without sun shine. It takes to much power for german winter. I will test model A soon, which will take 2/3 of the power from model B...
