ipxe speed with http

[NiKiZe]

I would recommend switching to iPXE native menues instead of using pxelinux
iPXE also supports scripting, and you can dowload the boot script over http, that way the server can be smart and do lots more then "just have a HEX file to match the IP"

iPXE has lots of changes over gPXE and the best is probably just to test how it would work for your usecase, I think there is lots of resources and examples here on the forum if you just search fro centos.
