poor performance with interop

[Peterboshra]

hello,
I have an application written in COM/c++ and produce interop,

I used this produced interop with the .net application and labview 

the interop with the .net application has excellent performance and no latency but the interop with the LabVIEW is much slower.

I don't know what the issue could anyone explain it?

any idea?!

You gave no meaningful information for us to help you.  What is this "interop"?  How did you implement it (ie share your code)?
