You have hardware in your box that 6.06 doesn't support?

Most certainly its worth it, 2.2.5, while requiring a reconfigure, is both
faster and smoother than 2.1.5, a new stepgen option now allows the reset
pulse to be sent to the hardware in the same main loop cycle that does the
set pulse, this means that the main loop can be slower (it used to be a cycle
to set the step pulse, and then reset it the next cycle=2 cycles for one
step), making more time available for other things, and still able to drive
the steppers at a higher rate than before. Or said anther way, the steps
speed notches that can cause a stall because of the difference in the speed
from a one cycle change can now be made less, allowing higher actual working
speeds.
I used to hear my little micromill doing discreet speed changes that were
pretty obvious above 10ipm, and which are smaller increments and more
smoothly done at 20ipm now. With everything loose, I can move 35+ ipm, but
not of course under load.

Some of that bit of eternity can now be tuned away.
If you have a net connection to that box, emc version 2.2.5 is only a
"sudo adept" session away. That net connection is worth every penny of the
cost of the cat5 strung across my back yard & plugged into a port of my 8
port switcher here in the house. I can't recommend it enough. You could
also carry the box to the net, but that isn't near as handy as being able to
log into the continuous IRC session these kind people have, and get advice
for a problem in real time while actually on the same machine. Real Time
Troubleshooting, even if the trouble is PEBKAC. In my case it has been,
several times.
