Minimizing the delay for changing and updating WFM buffer.

 

I'm using PCI-6052E (programing: VC++) to produce repetitive signal. For example, I saved 3, 5, 7 volt in a buffer and sent repetitive stair-like voltage signals to another equipment (rate is about 30000 pnt/sec).
WFM_Op() fuction is used for that. And I just re-call the code when I want to change the contents of buffer, for example, 3, 6, 7 volt. 
The problem is that there is a quite long delay for stopping WFM_Op() and restart new WFM_Op() with changed buffer. 
How can I minimize the delay, if possible, to less than 100 usec?

I attached the function which I used to make WFM signal
