optimizing code hsdio

[Timothy 123]

Hi,

I am working on some labview code for testing ics using the nihsdio
driver. This program works with the pxi 6561 card.  I have
attached the labview code to this message. I am looking for ways to
optimize this code to make it faster. Also, which size of data is
optimimum for the fastest fetching.

Any suggestions to improving the speed of this code are welcome.

Hi,

I forgot to attach my code earlier. Here it is:

Hi Timothy,
Your fetching performance can be optimized by reducing the number of records.  Each record is DMA-ed individually (and incurs a DMA setup overhead).  Can you provide more information on the records you're acquiring and your setup (i.e triggering scheme)?  It may be possible to combine your acquisition into one record
