MATLAB .NET Builder Speed Degradation

I'm having speed performance degradation issues with MATLAB .NET Builder. All I'm integrating is a simple plotting MATLAB function. After I create a .dll and execute it in C# Visual Studio, there is a significant time delay. Is there a solution or workaround to increase the performance speed?

Thanks,

Amanda

Could the "significant time delay" be the time required to initialize the MATLAB engine? The time would be almost exactly the same as is required to start MATLAB as a stand-alone program.
