I have mach on a bunch of different machine and it is real difficult to get anything useful out of it past 60KHz. I was running 60-65 on my CNC mill but with the new MachStdMill screen set I had to lower that as I was having glitches. Thats a decent speed AMD 64bit processor in there (And the last AMD I will ever buy)
Next machine is my Hercus CNC lathe. It is running a CoreDuo at 2GHz. I also have a hard time getting even up to 45khz. Get glitches there too. Need to go through the system and optimize and see if that helps.
I also have it on my little cnc lathe but that runs a smooth stepper so the point is moot.
Top kernal speed really depends on the motherboard and is the biggest variable. Some boards run great, some not so.
