I have 100% uptime on a small I3 ubuntu server with 85 seeds on it.... Then I have an Rpi (model A) running Raspbian with 10 seeds; Rpi randomly reboots on me about every 3-6 hours, sometimes more frequently.

Other than the reboots, seed performance is consistent between both workers. ~360kh/s a piece, W/U = ~9.8
