VC15 notes:
VC15 is backward compatible to VC14. That means, a VC14 module can be used inside a VC15 binary (for example PHP VC14 as module). Because this compatibility the version number of the Redistributable is 14.1x.xx and after you install, the Redistributable VS2015 is updated from 14.0x.xx to VS2017 14.1x.xx (you can still use VC14).

Documentation: http://httpd.apache.org/docs/2.4/

When you have hangs, slow traffic and/or when having in your log entries like Asynchronous AcceptEx failed. You can try the following settings:

AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off
