WCRT - Win32API based C Runtime Library

I used libctiny in one of my applications, and I was wondering what performance impact does this have on the application speed, I have two measures in mind, loading speed and processing speed.
loading speed is the speed in which the exe is loaded in memory, and processing speed is the speed in which the application can do its processing.

After thinking about both, I couldn't come up with a single reason that makes the smaller exe(using libctiny or WCRT) faster.
If this is the case, I'll stop using it and I'll link statically to the CRT.

What do you think?
