It ought to be around 1000, I think. Some earlier versions had uboot configs that did not run the CPU at full speed. I ran into that on Robert Nelson and early machinekit kernels. Bumping the CPU up from 300 MHz to 1000 helps a lot. I've been testing CRAMPS boards using a Beagle Bone (at 1000 MHz) and connecting with ssh -Y, and it is tolerable. There is some significant delay on the jog buttons. It gets worse if the 3D display is up, if you click to the DRO tab it cuts the load. This is using the machinekit / PRU setup, software step generation would likely be a dog.
