Hi everyone,

 

I searched the forums, but I could not find an answer to this. Attached are my test results for testing my disk speeds. You can see that when I write to the cache share it has a huge performance decrease. When I write directly to the drive (`/mnt/cache`) you can see my speeds are incredibly improved.

 

I am running the disk speed test suggested from this post. I am also running Unraid 6.5.3.

 

Any thoughts on why the share is so much slower?

Added what version of Unraid I am running

IIRC this happened before recently, i.e. for some reason on the latest unRAID releases dd write tests to user shares give extremely low results, but if you do an actual copy, e.g., from your desktop to the same user share performance is normal.

Yes, I do recall correctly:

 

Thanks @johnnie.black! My network transfers were also slow, so it was just a coincidence that `dd` was producing slow results as well.

 

I continued some troubleshooting and this seemed to resolved my issue:

1. I enabled `Direct IO` per this post
2. Once I had that enabled, my speeds were dramatically better over the network (`dd` was still slow per your bug suggestion)
3. Some docker containers failed to start though, so I followed these steps to delete the Docker image and pull everything back down again

Looking good now, thanks! ?
