One more thing that I forgot to ask,

What does this mean exactly, what performance loss.
Without PF system must work with equal speed or faster. Catch is that you must have enough of RAM otherwise it will fail loading
applications, etc.

Also DO NOT USE PF ON FLASH DEVICE. You can use it only if you need some of performance counters functions available, and in no
other circumstance.
