How to change variable in base workspace without blocking the thread?

I am trying to link an arduino to my simulink model and let the arduino send messages to change variables in my simulink model. The receiving end goes well with the serial receive block however I do not know how to change the variable in the base workspace without blocking the thread. If I use assignin or evalin it shows with tic; toc; that it takes around 0.0003 seconds, however the screen freezes for around 0.2 seconds when the method is called. So this method is not an option.
Then I tried using batch to run those methods it in the background or parfeval to run it in parallel, but they are both making the program even slower.
So my question, is there a way to target variables in another workspace without blocking the simulink thread? Or is there a way to queue the change of the variables since I don't need it immediately until a moment where not a lot is happening?

The real question is, why are you trying to change variables in the base workspace continually?

Are you using the Simulink Support Package for Arduino Hardware? I have not used this myself but I would be surprised if it didn't allow you to pass data from Simulink to the Arduino hardware and vice versa. If you're not aware of that support package, open the Add-Ons Explorer (in the Environment section of the Home tab on the Toolstrip) and search for "Arduino".

I'm not certain, but if you use the tools provided by the support package you may not need to involve the base workspace at all. That could avoid the 0.1-0.2 second "halts" you described entirely.
