Yeap agree... I turn off the indexes because an out of date index is useless as well as the indexes returning crap. MS's implementation is painfully hard to manage with the GUI (when you are talking thousands of extensions).I had an idea that I learned when working with large SQL imports - - TURN OFF indexing on the target drive:\Folder during the copy and reenable if so desired. Also reconsider indexing content - - usually non-productive but time consuming.
Looking at my config, the files for Index Search are kept at C:\ProgramData\Microsoft.I haven't done that yet. It may improve performance slightly, but what I'm seeing is obviously a very drastic change from what is capable between the drives to the horrible slowness and system lag. I very much doubt simple indexing is the root of the problem.
now I am constant under 100% diskusage, even if I coppy files from C:\ to C:\just disable your dvd drive in the Device Manager and it will stop
I've had a Windows 8 machine for 6 months. Its been perfectly fine until 5 days ago, when I started getting the 100% disk utilization problem. I've read through this thread, and there is one thing I don't think has been understood..the disk is NOT actually being used at 100%. It just says it is. When I add up the resources in use, the disk usage typically comes to 3-5% even though it says its at 100%. How Win8 handles resource management I don't know, but I generally can't do anything until the disk says its not busy (even though it actually hasn't been all along).That is absolutely my fault for not making that clear, but you are 100% correct. I was not actually expierencing that amount of disk usage, BUT it was reporting and acting that way. If you listened to the drive though, it was fine.
I've found two things that sort of help..meaning the problem is still there but it seems to clear in a few seconds instead of 5-10 minutes. I assign HIGH priority to anything I'm running, and I keep a valid disk in the DVD drive. I tried disabling the DVD drive but that didn't seem to help.
I'm testing a few possible sources for the problem at the moment. I'm rather suspicious of Flash Player, and there also seem to be rather a lot of update notification jobs in memory (even though I've got everything patched to most recent updates).
People have been reporting this problem pretty much since Win8 first came out, but there just does not seem to be any common factors, and I can't find any sign that Microsoft are looking into it.
Hopefully 8.1 fixes things.
