After the update, it looks like the NAS is again usable. Performance is still affected, however: file transfers are much much slower.
The slowdown likely occurs because the symformsync process is apparently not set to have a lower priority than other running processes, such as smbd (SAMBA - for windows networking).
Is there any way to set the symformsync process to run with a lower priority? I tried SSH-ing into the device and doing it via the Linux "nice" command but it seems that the distro on this box does not come with this command. In fact, I wasn't even able to check the current priorities of running processes with the "top" command... the priority ("nice-ness" value) column is missing.
Any ideas on how to make this happen?

Re: High CPU and memory utilisation
Hello FlixFlix,
I understand that you would like to have Symform run as a lower priority. All three of the Symform services run in 'Nice' mode. You can check this in the TOP, by looking at the STATUS column. You will see a N listed on each of the Symform services.
Thank you,

Yes, I was able to confirm this. I just don't understand then why the performance hit. Regardless of cause, the situation is pretty clear:Symform wrote:All three of the Symform services run in 'Nice' mode. You can check this in the TOP, by looking at the STATUS column.

- With SymForm enabled, file transfer speeds max out at 20-25 MB/s.
- With SymForm disabled, files come through at 40-50MB/s.

Re: High CPU and memory utilisation
I have constant high cpu utilization and memory usage even after all my files are synced on symform. Afraid at this point I to will be pulling the plug. Great concept, just wish is behaved a bit more reasonably.

Re: High CPU and memory utilisation
Got the similar issue (high CPU, mem) on TS410. Perhaps it may not suitable for this model.
UPDATE: Had to uninstall Symform to get the TS410 usable again.

Re: High CPU and memory utilisation
Installed on Ts-459 Pro+, contributed 1000GB to backup my data.
Uninstalled after a week because of poor performance and slowing down QNAP to a point that it responds really slowly to any request and consuming amount of resources that blocks even accessing admin interface on QNAP via www (timeouts).
Seriously... I don't understand how a files syncing app can slow down 2x1.8Ghz CPU, 1GB RAM machine.
Great idea, really poor execution.
