Buffer size warning in simulink

Hello,
I am running a search code with using fminearch. The function that fminsearch calls runs simulink to generate a final output where in Simulink I am running a control system simulation (figure below). Now the question is I am getting this warning multiple times, and I am not sure if this affects the final result or not:
Warning: The specified buffer for 'MRFT_2param_optim/Delay' was too small.During simulation, the buffer size was temporarily increased to 2048. In order to generate code, you need to update the buffer size parameter

you need to click the ling of the buffer to see what block have this problem after that you are going to block setting to adjust the sample time to 1

The delay block fills up a buffer with samples until it reaches a duration of one time delay specified by the block parameter. Once this is done, it will begin outputting the signal.
If the sample time was very small and the time delay was relatively large, then Simulink may need to re-size the buffer in order to hold one time delay. While Simulink can perform this operation, the generated code must use fixed buffer sizes and cannot perform this without using a bigger buffer

Thank you for the explanation.
could you tell how one can increase the buffer before starting the simulation?
