LabVIEW RT runs slower and slower

[alexwu1017]

Hi,

I runs the same DLL program on LabVIEW RT several times.

But the CPU load becomes greater in subsequent runs.

Can anyone give me some idea about it?

Thanks.

Hi Alex,

what is a "DLL program"? Which "LabVIEW RT" (aka target) do you use?

What exactly is your program doing? Do you have any open references/resources not being properly closed?

But the CPU load becomes greater in subsequent runs. Can anyone give me some idea about it?

Most often it's a bug in your software…

Not without seeing some (or better, all) of the code (VI's or zipped Projects only, please, no pictures).  You appear to be leaving some garbage behind when you stop the program, but without seeing the code, we can't begin to "guess" what that might be.

Thank you very much.

There found some memory leaks in code.

I think this issue comes from it.
