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
