Performance Fails, Realm Purchased for "Ten People"

So having purchased a realm "Capable of Supporting Ten Players" we are getting performace issues on our realm when only two people signed in attempt punch 2 bow flight, i understand chunk generation will give the server a bit of a performance hit having to generate terrain concurrently using the world seed while players and the areas around them still need processing, but even flying back over pre-generated terrain is causing game hangs and taking minutes to render, while causing game hangs for all connected, i can only imagine this is due to lack of resources or access speeds to whatever storage solution provided to each realm (no doubt using some magic dollar saving recipe for whatever virtual system you have setup), whether it be a lack of virtual processors designated/cutting corners by sitting thousands of realm world files on sub par storage systems, this is an issue that i have no doubt needs addressing for more Realm Players/Customers than simply myself and those that frequent my realm, by all means, ten players using the current setup would be fine if it were 10 children learning to use a keyboard and mouse building block dirt huts around the game spawn area, but considering the platform you are trying to support here - worlds capable of flight, complex redstone, mob caps that realms cant currently support & currently no limits on entity cramming (as it stands i can even bring the realm to its knees in a matter of minutes with a septa cave spider spawner i knocked up for the sake of it over the past two days just for proof of concept), and the problem is not to do with the world file or "my wifi connection" as sub par service support would like to regurgitate, we deleted our world and created a new one, i get full 100 megabit down and have a solid 40megabit up fibder connection, as do the rest of the realm inhabitants, we have even kept terrain generation to a bare minimum to keep the world file as small as possible.

TLDR; Realms need to evolve along with the Win10/MCPE edition to support rapid chunk loading/creation with the recent release of ability to fly & also be given enough resources to as advertised support a world containing ten players who know how to play minecraft.

And if im willing to complain about it i also believe in putting my money where my mouth is, so if need be im willing to volunteer/sacrifice my realm/time as a test subject if performance analysis is required as it is quite possible for me to replicate these issues at will and would be happy to contribute to others receiving a better experience.
