How to avoid marshalling and overcome performance issue?

1 New Member
HI,

I have some code which I am reverse engineering. Here is one module which is used as calculation madule and marshalling is used in it. But, still there is performance issue as the CPU time the module is taking to deal with the unmannaged data through dll and execution is much more. Is there any way to avoid this marshalling? I also wants to learn more about marshalling. Is there any link from where I can free download any ebook or something?
