How does it go in terms of timing / cycles?

I am highly interested in things DMA for 6502 based systems. Although I've chosen VHDL as my development "platform" rather than Verilog - to my understanding the main concepts remain fully valid across the two. With DMA I basically need consecutive writes for one of my projects and am very curious how fast and in groups of how many bytes could this be done in a given time frame.
