I am using Labview Vision acuisition Vi in Vision Express plattee with IMAQ PCI-1428 to collect image. The camera I am using now is a line scan camera from UTC aerospace system. The plrobelm I am having now is if I set the image height to over 1000 (typically I need 2000), the starting time of the program is very slow, usually takes about 1.5-2mins. Once it started, it can run pretty well, won't lost many frames. I don't know where to find the problem (I am a starter with labview). Could someone with experience offer me some help? Thank you.

Are you creating a big buffer?
Tools => Profile => Performence can help you analysis the time used.

Thank you for mention the time analyzing method. I will try it and see where is the most time consuming part.
The buffer I created is 1024*2048*2*5 bytes, so 21 MB. Is this too big?

No.
What version of LabVIEW are you using?
What OS are you working on?

The Labview I am using now is 2012 SP1 (32 bits).
The OS of the computer is Windows 7 Home Premium.

Is your OS 64 bit?

Yes, it is a 64 bit system. Does this mean I need a 64 bit labview to increase the performance?

You can if you have more than 4 GB RAM.

Thank you for mentioning this. I think I will try a 64bit labview software becasue I actually have 10 Gb RAM on this computer.
