Hi Kevin,

I seperated DAQmx Write, start task and clear, each function in VI and i timed only the call DAQmx Write the same problem.

I tried to update the frimware of cDAQ, to connect the cDAQ directly with another PC (Windows 7) and i still have the same issue.

You're still measuring the overhead of all the config operations because you're feeding in a Global channel.  Use the technique you showed in msg #5 where you explicitly configure and start the task *before* you start measuring execution time.

ALERT! LabVIEW's subscription-only policy came to an end (finally!). Unfortunately, pricing favors the captured and committed over new adopters -- so tread carefully.
