Windows 10: Robocopy making disk access very slow

Hello ,I am using Robocopy to periodically copy data media data mp4 video files from Local drive to network drive.When Robocopy is executing copy command, local disk access is very slow and becoming almost unusable to open it.Tried with different thread options 8,16,32 etc. but disk performance issue is not solved.Any reason why robocopy is hampering local disk performance so badly.?Thanks Sampath

100% disk utilisation slowing laptop

Hi Mara May,

Thank you for your assistance, I have had to type this in WORD and copy paste into the thread here due to all things through Chrome and Edge are so slow.

• Windows is always up to date with all updates.
  
• Norton Utilities is also up to date
  

• I have already done the following:
  
  • Tested HDD with HP Startup Menu and disk is 100% in order
    
  • Carried out SFC scan and corrupt files repaired
    
  • Did a DSIM restore health and no issues found-Disk utilisation is now generally below 50%
    
  • When using Chrome browser, to access this chat for example, its very slow with Disk utilisation at 10% or so but Memory at 55% with Chrome using most of it always.
    
  • So the problem is partially resolved except for when using Chrome
    
  • With Edge the memory goes up to 62% and HDD 100%
    
  • Did you suggested :Methods” 1, 2, 3, 5, 6
    
• I have not done a “clean boot” as it scares me at this stage.
  

It seems to be an issue between Chrome/Edge browsers as when I use Office 365’s Outlook, Word etc, the speed is now OK. Also the Disk utilisation seems to be generally acceptable but memory high that may be slowing the laptop down?

I have had issues with Teams simultaneously in that it’s so slow but with Zoom its normal, coincidence?

I look forward to your further suggestions.

Regards

Robocopy speed question

I have 2 large files (total 210 GB) being copied by Robocopy between 2 external drives. Task Manager under "Disk" indicates a transfer speed of 30 MB/s.

A straightforward calculation indicates that it should take 117 minutes to complete the transfer. In practice, however, I am noticing a time to completion of about 250 minutes, or more than double the theoretical calculation.

Can anyone please explain this large discrepancy or, alternatively, suggest some way to improve on this performance? With Robocopy I use switches /mir /xo /mt:80.

All suggestions appreciated.
