This part wants to concentrate on

Main idea

According to an article from Microsoft the placement of shared libraries is crucial for a good start up performance. The article states that the load time of a library can be reduced by about 20% if it's located at the first search position (next to the binary).

It must be clarified if the findings can also have positive effects on the other platforms.
