I am using 6221 DAQ card, i am generating continous pulses in counter0 but the problem is start task is taking lot of time around say 10-15secs. this VI for generating pulses is called dynamically.
Attach your vi, or just a screen shot (jpg). Remember, the very first time you run a program that accesses your PCI cards, it can take a long time - after that it should be fast.
