    I am seeing the same problem with 10.8.3.


    I have a 27" iMac,   3.4ghz i7,  3tb Fusion Drive,  16GB ram.


    The issue is as reported slow performance and a number of beach balls,    I can see it's not a processor issue, I run tray icons to monitor this and (Terminal > Top) shows 99% idle.


    What I have found using BlackMagic drive speed test is that sometimes I'm seeing <5MB read/write,  whereas normally it circa 300MB r/w.


    Iv'e reset PRAM to no effect.    


    It's definitely an intermittent disk performance problem,  e.g. opening a VM in Fusion from a frozen state used to be sub 1second and now the load bar crawls across.


    I think I'll give it a couple more days to see if an fix is forthcoming,  otherwise I'll flatten the machine restore from backup and go to 10.8.2

    Maybe your HD is about to die.

    I took the plunge and put a SSD in my laptop.

    It is mac nerd heaven.
