VLIB execution on PC

Hi,all
The Vlib includes a pc version, but I find its execution on pc is
very slow.  I suspect it is a debug version.

In my opinion, many applications using VLib require cross
platform. If VLib is slow on PC, I have to develop applications on PC
using my own library or other libraries. It is not a good idea for
developers.

Is there any way to avoid this?
