I don't think you can, not really. Practically all the slowdown you see comes from increasing levels of abstractions, and basically all good abstractions have a performance cost.

Abstractions in general buy you faster development and more reliable/stable software. UI abstractions buy you intuitive and easy to use UX. All of these benefits define the modern era of software that has spawned countless valuable software programs, and it's naive to think you can skip the bill.
