Strange function slowing down my program

I'm using Visual Studio's performance analysis to determine why my program is slow. The function that takes up 25% of the exclusive CPU samples is a function in clr.dll called

?JIT_New@@YIPAVObject@@PAUCORINFO_CLASS_STRUCT_@@@Z

What does this mean? (I'm using Visual Basic 2012 if that matters.)

You're probably getting hit by excessive boxing (hence 'struct').

This question is essentially the same as the one here.

Short answer: JIT_New is allocating memory, and maybe occasionally getting hit with the garbage collection time.
