Very Slow transfer speed with cache drive

[Maddeen]

Hi there,

 

after finally setting up anything I need, today was the day where i first copied a big file (8,5GB) to my unraid server. 

The speed was - honestly - very disappointing. 40MB/s at peak in 1Gbit/s network is far away from acceptable especially with a cache drive. 

I found a lot of YT-videos where people getting the "normal" rate of about 100MB/s with unRAID and the cache drive.

So I think I have a failure in my config or there are some optimizations needed - hopefully. 

 

Background: My "unraid-server" was a simple Win2019 Server 10 days ago.

No changes in hardware or network - and back in these days - transfer rate were always 90MB/s in average - most of the time about 100MB/s. 

 

I attached a screen where you also see the macOS activity monitor validating this worse transfer rate. 

 

Share- and Network-Settings also attached.

 

I appreciate any help - thank you in advance.

I am having similar issues, only getting a max of 30MB/s write speed to cache drive. keen to see if anyone has a solution

Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post.

Here you go - my ZIP file. 

But it seems, that the problem is gone --- I made some more big file transfers to the same share "filme" and got the expected speed of 100MB/s - 118MB/s in peak!! 

See screenshots attached. I'll review this at any following transfer and give a feedback.

Maybe you find some failures of my setup in the diagnostic ZIP

Thank you

Your syslog is being spammed with these once per minute:

May 15 07:49:55 UNRAID s3_sleep: Disk activity on going: sdc
May 15 07:49:55 UNRAID s3_sleep: Disk activity detected. Reset timers.

I'm sure I have looked at other syslogs where a user was using s3_sleep plugin, but I never saw that behavior.

 

What happens if you uninstall that plugin?

I had some sleep issues and activated the debugger of the plugin. Seems that it writes the logs not even to the dedidacted folder /boot/logs/s3_sleep.txt

But I resolved those problems and deactivated the debugger now.
