    Hello

    I am running Windows 7 and Parallels Desktop 9.
    Since few week the disks access are very slow, too slow!
    I checked some parameters:
    now VM RAM is 3GB (total 8GB), disk C: not full, task manager show no process with CPU or RAM usage too high (not swapping).
    The problem is with the C: disk and Mac side disk.
    The VM is on an external disk directly connected on FireWire.
    Disks are not compressed, I tried with coherence activated or not...

    What can I check now? It is too slow to be usable: I launch the explorer and I can make a coffee, drink and come back!
    I don't have this trouble with my Linux nor my FreeBSD VMs.

    Happy New Year
    Regis
