I remember that I used ONDEMAND in the past and it was predefined behaviour with MDV 2009.1, if i remember well
I had no slowdown with ONDEMAND vs PERFORMANCE, and I don't remember any freezes or other side-effects...
While the most developers affirm that ONDEMAND is NOT more needed, some users could find instead that this mode
while doesn't add any noticeable slowdown, if helps to maintain our PC cooler, and this could be not a bad thing at all
If some of You will help me with some testing, I can prepare the same kernel versions also with the value ONDEMAND as default in all flavours
and I'll store these kernels into different paths so You could install the default kernels flavours and these ONDEMAND enabled to observe the differences using your PC in the real world...
Then, if the results from these experiments will be good, with no slowdown and regressions, we could change the default behaviour of some kernel flavours, for example all nrj-netbook or also nrj-desktop, with ONDEMAND enabled as default value
For Windows there are some benchmark about using cooling apps like cpuide, cpucool, or others that act like ONDEMAND on linux kernel

bye, NicCoLet me know if some of You are interested in helping us with testing this stuff in many different following kernels
