Yes Mach3, I am using my own screen design but I have not done much to the Diagnostics page yet so it should be there. On my screen it is lower right but I will go and load the standard screen set and see.

Well just loaded the standard screen and its right at the lower right of the Diagnostics screen, you should see the DRO for Fast Jog Rate, just click on it. change to 100 and press enter.

my screen does not look like that it looks like, if you look at general discussion and mach3 screen (where they make new screens for mach3 ) and look at the diagnostic sceen you will find what my screen looks like . (sorry for the delay my neibourg invited me for dinner)

yes  the slow jog will go faster at 100% . but when i used the fast jog it went faster than the slow jog and i could use the slow jog to machine at the same time use the fast jog(shift + jog ) to move the tool out of the cut faster than the slow jog

 I am not sure I fully understand what you are meaning but if I understand you are saying that when you have the slow jog DRO set to 100% it is still slower than it used to be. If this is a correct understanding then I think you must have changed your motor tuning or possibly you have reduced your pulse rate from say 45,000 to 25,000.
I am no expert on Mach but my understanding is if the slow jog rate is 100% you cant move any faster as that is what your motors are tuned at.
 One other thing to check is enhanced pulsing is enabled as this may slow things down as well.
