It is all library and hardware specific of course... Svgalib for example
has almost no hardware acceleration (including blitting) support.
XFree86 *has* hardware support, but being able to *USE* it is pure
wizardry (what options to set to get it for some versions of XFree86
might be different for other versions and so on).

You can't do better because of the hardware. DMA is faster than
programmed I/O, that's all. No matter how cool running shoes you buy or
how sophisticated a bike you buy, even my poor Hyundai will leave you
WAY behind. Don't even think about the Ferrari.
