When I use blocks from the Robotics System Toolbox, such as ROS Publish or subscription blocks, the initialization time is approximately 30 seconds in the simplest model (subscribe -> Bus Selector -> Display). Everything else is very fast.
A friend of mine has a non-measurable initialization time on a weaker computer. I use Matlab R2017a and the ROS Indigo Gazebo VM on a laptop with an Intel Core i7-6500U with 16 GB of RAM.
Is there anything I can do to make it faster.
Thank you for your help and happy Easter! Benedict
