    Not wanting to HJ the OP's worries/thread, but I too see this cfprefsd in activity monitor, but the part that worries me is that sometimes its doing not much at all and other times its showing 92%... is _that_ normal?  Likewise, since installing Yosemite 10.10.1 and even with the 10.10.2 update, I'm also seeing a _massive_ slowdown in Apple Mail and mail sometimes shows 90+% or "Mail Not Responding" in red while the spinning beach ball is going.  Otherwise, the machine seems to be running normal until I try to open, read, and reply to an email.

    I am a bit puzzled by this process as well. OK if it is needed for some processes that I needn't worry about but why does it run just after booting the computer under another user name? I am looking at the activity monitor because my Mac has slowed down markedly in recent weeks. I seem to notice that there is permanent disk access even if the computer sits idle with no application running.

    I have had this behavior and it was my system hard drive "soft failing". I backed it up (took forever to do), and a few days later it failed completely. The backup was a bootable copy that worked great and at full speed.
