Resolved Question

Computer slow when running several tasks at same time

May 19, 2016 12:30PM PDT

Windows 10 home, v1511, 3.0 GHz CPU, 8 GB Ram, 64 bit. If I copy a large file, say 6GB, from one folder to another, and then try to open the Internet or my email program or both at the same time, there is a very long delay before I see any action. When I look at task manager while this is happening, it shows CPU usage very low and also ram usage below 30 percent. And of course the 'task manager' also takes a long time to open. Is this normal for “my” computer or is there something I can change to improve the performance. I went through the “Black Viper” suggestions and did same, so some services were disabled. When "not" copying, Internet and or email opens rather quickly.

Thanks in advance for any suggestions

Can happen here too.

And I have a fairly nice monster machine. In the case I worked on this morning the disk I/O was maxed out leaving plenty of CPU and RAM free.

Fix? Run a few less tasks.

Copying files soaks the disk I/O so nothing wrong about this delay. It's part of today's computing design.

Experienced same thing on Windows 10

I observed this thing mostly when using Windows 10. Never faced this problem on Windows 7. It is mostly due to the new computing design that Microsoft is adopting. Do not depends on the machine.

Here I find copying in prior versions to soak disk i/o

And here you claim it didn't happen on 7. If you upgraded and left drivers to Microsoft, you will see even less happiness.

Update - Reinstalled win10

on May 21st, couple of days after original post. Issue resolved. Something must have gotten messed up because now when I copy a large file, computer does "not" slow down. Everything works as I would expect, no slow down.

Disk I/O on a fresh install.

Is also soaked over Microsoft's penchant for implementing indexing. If you pull up Task Manager you can usually spot the bottleneck.

I've seen this on every version of Windows but as folk run 10 they usually claim it's an W10 issue when I see it as normal.
