I am using a SCXI box with 64 channels, when I read the data I append the new data to the previous data, I am sampling at 500 samples/sec. As the old array becomes bigger than 1000 rows which is 2 secs of data, the processor usage is going up to 50% and from there onwards it is degrading more.If I dont append the data just load the new data into my array the processor usage is only 5%.I need all the data from the 64 channels and I run the appending funtion atleast 10 secs before I clear and add the new data. I am attaching my program with this message, Get data state in my program is where I am appending the data. There are couple more SUb VI's which are needed to run this program, but atleast the main VI should give an idea what I am doing.
Thanks,
Mudda
