Benchmine is a open source software to create Minecraft Pocket Edition Server. I'm not going to provide you the executable. For all we know the networking of MCPE we owe shoghicp and I respect him for that. The program is tested only on Linux. The program is pure development so do not ask if I could create a server with the program. if you want to contribute something in the repository will put the link at the end of the post.
When you start the server, you can see the title in the MinecraftPE server list (Title = BenchMine Server)
