Excel 2013 vs Excel 2010 Ole or interop performance

Hello,

It appears to me that Ole or Interop calls via c# and dotnet (2.0 or 4.0) are much slower with Excel 2013 than with Excel 2010.

I disabled the accelerated graphics option of Excel 2013.

I call Ole quite a lot (I need to) I already write large data in range. The problem persists, every Ole call (or interop, tested both of them) if much slower. It is not a protected speadsheet issue.

Any idea, how to circumvent that ?

Thanks in advance.
