NAS VERY SLOW ≈ 1MB/S UPLOAD

My NAS server is extremely slow at writing data... slower than it should be.  We're currently writing data to it at about .05-4MB/s.

 

Here's the sitch:

- We've got the Storinator 45 drives

- Everything is looking "healthy" on the unraid interface

- I don't have turbowrite set up, but even without this feature, the NAS is being way too slow

- I'm not using the cache pool either, but again this write speed is abnormal

- Using third party apps to write to the NAS (chronosync and carbon copy cloner - both up to date)

- Slow on all computers connected to the NAS

- Have checked the connections to the Network and have ruled this out as an issue

- I have 4x 16TB EXOS drives from Seagate used for storage + 2x 16TB EXOS drives used as parity drives

Sorry what I meant is:

 

1. I copied 250gb to the cache pool. This wrote at 70MB/s

2. Once this was done I used the 'Mover' to move the data from the cache pool to the array.

3. As this was moving, the CPU spiked from 5% to 100%

4. The NAS was not being used in any other way at this time

What did the 250GB (I assume you mean GB--gigabytes--  and not Gb--gigabits) of data consist of?  Was it 250GB of 1KB files  or a few 25GB BluRay .ISO file?  Unraid's file over head on HD's will be a major performance hit for large numbers of small files.   (I have a very cheap SSD cache drive and I see see write speeds of 90MB/s for Bluray ISO's directly to the cache.)
