Ultra 6 Performance question
I had this for about 4 years and was never happy with its speed. And I just want to confirm if the speed I'm getting is normal.
ReadyNAS Ultra 6 with three 3TB disks (2 seagate and 1 WD) in X-Raid 2. Jumbo frames are off (actually hurt transfer speeds in my case) and log is turned off. Write caching is on. Network ports are set to auto and reports that gigabit is enabled. All switches and routers are gigabit capable and enabled. All Cat6 cables.
When transferring a folder with a lot of files, both small and large, I'm getting around 20~30Mbps. When I transfer the same folder to our file server with RAID-10, I get about 100Mbps.
We originally purchased the NAS hoping that it would serve as our file server but the performance is so slow that we just use it as backup storage.
Is the speed I'm getting normal?

Re: Ultra 6 Performance question
How are you transferring the files? (cifs?)
If you have a chance maybe run NasTester (http://www.808.dk/?code-csharp-nas-performance) and share the results here.

Re: Ultra 6 Performance question
Yes, cifs and dragging and dropping to mapped drive. From Win10.
Tried the program and getting this error when using drive letter.
An error occured: Could not find a part of the path 'N:\1test.tmp'.
When I use IP address or network name, I get this,
An error occured: The network name cannot be found.

Re: Ultra 6 Performance question
Got the tester working. It gives those errors if I run it as administrator???

Re: Ultra 6 Performance question
Read speed is as expected.
The write speeds look about 1/2 what I'd expect to see with an ultra-6 running single redundancy xraid.
You do have the write cache enabled?

Yes. Mentioned it on the original post.

You mentioned the brand of the disks, but not the model.

Re: Ultra 6 Performance question
I just checked off write caching and it didn't make any difference in write speed. Perhaps the write caching isn't working?

Re: Ultra 6 Performance question
Maybe try disabling the journalling also.
Have you looked at the SMART stats for the disks?

Re: Ultra 6 Performance question
Journaling was always off. And the Smart all checks out. Do I have to reboot the NAS after changing write caching? It didn't auto restart.

I'm not sure, but it wouldn't hurt to reboot it.
If its been up a long time, its possible that a reboot might improve performance generally though.

Re: Ultra 6 Performance question
Rebooting after changing the write caching doesn't make a difference. What would be the reason for write caching not having any effect?

Do you find a solution to your performance problem? My Ultra 6 (Version 4.2.28, 4x WD30EFRX, X-Raid2, Smart OK, only write cache on) has similiar performance problems with cifs file transfer. (~30 MB/s write / ~60 MB/s read)

Is journalling disabled?
Are these large file transfers?

File size ~ 4GB per file.
Journalling was disabled. I switched it on and off, restarted the NAS now it works normal with read ~100MB/s and write ~80MB/s!
Thank you for your response.

.
That's great news (though I am thinking it might have been the restart that did the trick).
