  1. Thanks MrRon! So is the CPU low while Defraggler is running on your test machine? If you need any more system info or if there's any way I can help out, then please feel free to give me a shout on the personal email I used to register this account. Cheers, Chris.
  2. Hello, This is running very slowly for me too: Defraggler version 1.14.159; My laptop has a Core 2 T8300, RAID 0 hard disks, Vista Ultimate 32bit SP2. When running Defraggler is sitting near 50% CPU, practically occupying an entire core, which seems odd for what I imagined to be an I/O bound process (is there any polling going on?). I used Process Explorer to get a thread stack and these two appear quite frequently: ntkrnlpa.exe!KeWaitForMultipleObjects+0xabc ntkrnlpa.exe!KeWaitForSingleObject+0x492 ntkrnlpa.exe!KeTestAlertThread+0x78 hal.dll!KfRaiseIrql+0xd1 hal.dll!KeRaiseIrqlToSynchLevel+0x70 hal.dll!HalEndSystemInterrupt+0x73 hal.dll!HalInitializeProcessor+0xcc1 Defraggler.exe+0x20e29 Defraggler.exe+0xf1a02 Defraggler.exe+0x10a848 ntdll.dll!RtlEnumerateGenericTableWithoutSplaying+0x424 ntdll.dll!RtlEnumerateGenericTableWithoutSplaying+0x4a ntkrnlpa.exe!KeWaitForMultipleObjects+0xabc hal.dll!KfLowerIrql+0x64 ntkrnlpa.exe!ExReleaseResourceLite+0x161 ntkrnlpa.exe!KeSetEvent+0xb2a ntdll.dll!KiFastSystemCallRet Defraggler.exe+0xfcd49 SHELL32.dll!Ordinal264+0x3f1 SHELL32.dll!Ordinal236+0x4f2 iastor.sys+0x76f75 SHELL32.dll!Ordinal205+0x3a53 Defraggler.exe+0x120055 Like others here, defrag time is many hours. If this performance issue gets fixed then this will be a fantastic tool. Cheers, Chris.
