Application Builder Very Slow. How much RAM is required

[Int_man]

I running LabVIEW 8.0 on a Windows 2000 PC. The PC is a Pentium 4 300GHz, with 1 Gb of RAM. I have a specific application which has 400-500 VIs and the built time has escalated from approximately 3 minutes to over 60 minutes. I have tested it on another computer with similiar hardware and I get the same results.

During the Application building I have observed that hard drive light is continually on so that it appears that the computer is using virtual memory. The LAbVIEW VIs are stored on the network and LabVIEW program files are stored on the local srive.

My questions are these:

1. Could I actually be running out of RAM during the building process?

2 What are the computer requirements for LabVIEW 8?

3. Is 1 Gbyte of RAM enough RAM to build large (400-500 vis) applications?

Thanks

Hi Int_man,

1. Unless you notice CPU usage skyrocketing to 100%, probably not.
2. "LabVIEW requires a minimum of 256 MB of RAM, but National Instruments recommends 512 MB of RAM." This information is available in the LabVIEW 8.0 Release Notes
3. The size of an application usually takes a back seat to array/cluster sizes. Branching large arrays and passing between local variables cause memory usage to increase X-fold. To quote Dennis, " The amount of RAM used is more a function of what your program is doing and how it is doing it than the size of the source files."

I recommend taking a look at the Faster build discussion forum. There are many helpful suggestions for optimizing the App Builder build time.

Cheers.
