I offer mach3db on either a shared colo server or a dedicated colo server.
If you get multiple dedicated servers you could theoretically configure a master-master or master-slave arrangement.
The reason it's so fast is not just because it's on a dedicated server.
There are actual differences between postgres and mach3db.
I invite anybody who wants to test mach3db to reach out for a free trial account.
I think the speed will surprise people.
