Hi Phil,
I am running a Dell Desktop with a Pentium 4, 3.2 GHz processor with 512 MB of RAM. Are you seeing 30 ms? I just looked at your attachment and it still shows around 70ms. If you are seeing 30 ms per run of DAQmx Read, this is what we would expect, correct? (1024 Samples / 34,133 Samples/sec = 30 ms) So now we just need to work back and see what the difference between this test1.vi and your original VI.
Where you store your VI should not affect its speed of execution. When you run a VI, it is loaded into local memory.
Regards,
Sean C.
