Long using time #54
Description
Not sure if this is actually an issue, but it seemed like a significant time to me so thought I would ask about it.
I tried out the new @time_imports macro in v1.8.0-beta1 and found that almost half of the load time in ControlSystems came from NonlinarSolve. Also ran it on NonlinearSolve to see how it looked there, and it was faster than the time reported in ControlSystems (3.99s vs 6.58s).
I'm not sure if there are things that can be done easily in NonlinearSolve? And maybe it is really ControlSystems that needs to do something since the load time was worse there?
