Performance of mathscript in RT scan mode of CRIO 9075

Hello, 

 

I am working in active vibration control field. I want real time control of vibration. I am new with Labview and working with Matlab for last 3-4 years. For real time control purpose, I am using NI 9234 AI card, CRIO-9075 Integrated Controller and NI 9263 AO card. I have .m code for controlling process.  I am using RT mathscript module to get required data. The problem is it is taking 45-50 ms for 1 iteration and i am loosing lot of data in each iteration. When I am running same matlab code in my system (laptop) with same inputs, it is taking 2-3 ms and in matlab itself it is taking 5-7 ms. Why it is taking time using CRIO-9075? How can i improve the system? Is there any other fast controller or any other better option for this application?

 

can anyone help me? 

 

Thank you in advance for the help.
