Initially being substantially higher latency than the hypervisor breed, over the last year or so huge progress has been made in terms of performance delivered on Intel platforms in particular, but also on ARM platforms: I recently tried an RT-PREEMPT kernel on a Raspberry-2 and it delivers slightly better latency than Xenomai on the Beaglebone. Migrating transmission-daemon from RT-N16 to Raspberry Pi + Baby Monitor Lately transmission on my RT-N16 has been acting a little too unreliable. So far I've tried to use the PREEMPT_RT patch and to isolate a core and reserve it for the RT application. Also included is a MicroSD to SD card converter, which allows the MicroSD card to be used. That is how I came to the Tinkerboard with its gigabit dedicated ethernet and fast sd-card access. The most important characteristic here is the max latency which indicates the longest time it might take your Raspberry Pi to respond to an event. Using the Raspberry Pi 3 and add-on boards, developers can rapidly create industrial automation systems able to meet small shop requirements. The Pi itself is pretty lame as a robot controller. thanks,Quintin.
