I'm sure I'm not the only one that has a computer with the slows...but
Did a fresh install of Windows 10 on a
- Dell Precision M6800 (1 TB SSD + 1 TB HD; 24 GB RAM; i7 with (x4) Cores)
- Used Windows Recovery
- Keep nothing (wiped out all files on 1 TB SSD)
File Explorer, Browser are super slow
- 14 sec from clicking on the folder icon on the Taskbar to displaying the window with the File Explorer
- No software installed other than O/S
Updated all drivers from Dell
- First updated drivers per Dell advise (via website)
- Next updated all drivers per Dell Command Update that indicates update all for a fresh install
- Removed external monitor (in case it was a graphics card issue)
- Dell automated tests indicate no H/W failures
Checked Task Manager for processes:
- nothing that I understood as noteworthy
- no processes consuming massive memory of CPU
Checked Resource Monitor
- CPU is < 15% utilization
- Memory is < 20% utilized
- No significant network traffic
Performed a Clean Boot
Ubuntu 20 LTS works well
Began to use the Windows Startup Settings:
- Low-Resolution video: Did not help, File Explorer still takes 14 sec from click-to-window. Does that mean the graphics card / driver is not the problem?
- Safe Mode: Works pretty good in this mode. Didn't do thorough testing, but the File manager comes up pretty quickly.
- Safe Mode with Networking: Works the same as Safe Mode above.
Nothing I'm doing is indicating the root cause. There is no change in behavior regardless of what I've tried.
- How can a computer be slow if the CPU, memory, network bandwidth, and disk access are not near their maximum?
- What good is a process monitor like Task Manager or Resource Manager if they are not an indication of the usability of the O/S?
- What are other tools that can diagnose this problem?
