Hi, I've been using myrobotlab but am looking to migrate to ROS. SO I'm just getting started. Currently using Arduino to interface to 5 servos in a humanoid head including eye cameras as a starting point for some CV experimentation with object tracking and recongition. I've installed the latest version of 32 bit ROS on a Ubuntu 16.04.2 Mate system running in 32bit VirtualBox under Linux Mint. of course I expect that things will be a bit slower running on the VM. But Ubuntu is pretty responsive. I've built the Blink example and have successfully controlled the LED using ROS, but there is a several second delay from when I start the command to when the LED changes state. Same thing for the single servo example. It takes about 4 seconds from then I start rostopic to when the servo actually moves. Is this just due to running in the VM environment, or is there something else that I should be looking at to improve the performance. Obviously a 5 second latency from command to movement is going to be a problem:) If it is just due to the VM environment I have another machine I can sacrifice to doing a bare metal install of Ubuntu 16.04 on. Other than this perhaps being due to the VM installation is there anything I should be looking at that can reduce the latency?
