How to improve the performance of your WD MyCloud Device

WD MyCloud is a fairly useful device if you want to have a NAS attached to our network …


However once you start loading a lot of data the performance drops off dramatically … it seems to forever be that the content scan is forever building content or in a phase of always “content scan building”




Youtube Video detailing how to increase performance

Two articles have look at this namely mjd and  shortattentionspade.

After carrying out the below changes you should see an immediate improvement, this works until you need to restart the device.

The following advice is at your own risk. 

Turning off the two processes causing the performance issues, before begining you should understand your terminal and ssh

This will also void your warranty (however a factory reset should fix this if anything goes wrong)

  1. Through your browser, go to http://wdmycloud.local/UI/
  2. Login and go to settings
  3. Turn on SSH
  4. Open terminal on your pc / mac
  5. Type ssh root@(whatever IP address is of mycloud)
  6. Say yes
  7. Password welc0me (the o is a zero – the number and not a letter)
  8. Type /bin/sh /etc/rc2.d/S86wdphotodbmergerd stop – turns off poorly written thumbnailer
  9. Type /bin/sh /etc/rc2.d/S85wdmcserverd stop – turns off slow mycloud indexing.
  10. Exit ssh by typing in exit

The processes S86wdphotodbmergerd and S85wdmcserverd essentially consume all the hardware capabilities and make the device so slow.
