Using SIT connection manager with large simulink models is extremely slow

[Nacho_s]

Hello,

I'm trying to use a large simulink model in LabVIEW but once the DLL is correctly generated and the SIT connection manager is invoked to explore the model sinks, sources and parameters, it takes hours to generate the model connections tree. Afterwards, when the connections tree is completed, it is impossible to handle it because every operation performed takes a lot of time and memory (i.e. to expand a block to see which parameters are inside).

The version of SIT I'm using is 2.0.3 with LabVIEW 7.1.

Is there anybody experienced with large simulink models and SIT?

Thanks and regards.
