Priority Function for appdesigner during Simulink Interaction

Hello

Is there any priority function to call for during running simulink real time? I have been using appdesigner model which interacts with simulink designed model to get the real time data from the target PC and plot in the appdesigner UI. Since, the data getting from the target PC is per second is too huge which put other functions called during the process on hold/queue, until all the data sets are been plotted.

Also, is there anything equivalent to this in the latest version (R2019a)?
