SISOTool (Control System Toolbox)

Hi,

I'm using R2018b on an Intel Core i5-5300U @ 2.3GHz with 8GB RAM, WIN10, and the SISOTool from Control System Toolbox is running very slow when add, move or delete poles and zeros in the compensator editor. There is a lag of ~0.5s before any change can be seen in the compesator design window. This is annoying when it comes to fine tuning of a compensator. I can see that the SISOtool uses up tp 4GB of RAM and up to 90% of one CPU core.

I remember that the older version of the SISOTool, e.g. in R2015a worked much faster without any lag. I only remember that the installation of mozilla firefox can make the SISOTool of R2015a very slow which I guess is some JAVA-related issue. After de- and reinstalltion R2015a the problem was gone.

Can the issue in R2018b be solved by chaging the JRE version? Is this in general a known issue?

best regards

Moritz
