I needed inter-dimensional item transport that could keep up with 27 maxed-out Borers in my survival world. Here is the prototype that I came up with. Surprisingly resource-cheap (though very expensive on power), too. The creative strongbox represents the Borers. In reality, each borer would have its own chest, with a top output of 700 blocks per second, so you would only need one tesseract per Borer.
