I don't know how you do this with UISP but check the oscillator of the 
stk500. It may have been modified. This is the setting for running the 
clock of the Target microcontroller. Altering this frequency alters the 
speed of In system programming even if you are not running the target with 
this clock source.. Though i do not remember the maximum frequency that can 
be generated by the STK500, it is in the range of 3.xx MHz. This setting 
will give the maximum speed for ISP.
