Massive disk activity from 2pm - 3 or so, every day. This is a workstation running Win 7 Enterprise. An I.T. contractor manages the network and the workstations, group policy stuff, etc. 4 gig laptop running so many background apps (for security...) that it would squeeze even an 8 meg machine for resources. So, I've eliminated the following as causes:
- Symantec Endpoint Protection
- MalwareBytes (Enterprise Ed.)
- Win 7 System Restore (turned off, since I.T. re-images from a base loadout upon any major problems)
In task mgr, none of the above are using any CPU cycles when the disk thrashing is going on. I'm talking about thrashing so bad that when you type in MS Word or what have you, you get ahead of the laptop and it spits your words out in batches trying to catch up.
In task mgr when the disk thrashing it going on the there are CPU cycles showing for NT Kernal and an SVChost process will show a lot of on and off use of CPU cycles, though it's never up long enough to drill down into it and see what services it is hosting. I have the running process sorted by CPU cycle usage descending to see this.
When the swap file (Windows Pagefile on disk) was set to auto, things were worse. I've since turned it off, deleted it, rebooted w/ no pagefile and done a defrag, then set a pagefile to a fixed size of... I forget, I think 8 gig. That helped some, setting a static fixed-size pagefile.
I.T. contractor help desk no help-- scratch their head and say all scans are set to run off-peak in the wee hours.
Laptop is left awake but locked during off-peak to make sure it executes all off-peak scans and doesn't postpone any due to sleep mode. The off-peak scans always show clean results.
If it wasn't an employer machine, would probably have taken a ball-peen hammer to it by now . . .
