NAS Scan Speed Extremely Slow

Other then "visual" observation, two NetworkTrafficView (html) reports *attached.
(*attached ? at least I think I did, but I'm not seeing them ? let me know if they did not make it here.)

Wired via LAN (not USB). 10/100/1000.

Code: Select all

(Bump. Did my attachments actually make it up to you?)

Don't think the attachments appeared.

Is it slow in the 'building file list' stage, or the duplicate finding stage? I've found file discovery on NAS to be quite slow - looking into this.

I try sending them up, but depending ..., might not be able to get to them till Monday or so.

> slow in the 'building file list' stage

Yes, pretty sure that was the case.

(Well, this took me longer then expected...
And it still looks like its not working?
These are .html files (reports).
Upload attachment, Browse to the wanted file, it shows the file name, Add the file,... yet nothing seems to actually make it up here?)

Ah, I see - now that I see, "The extension html is not allowed."
So that's why.

So let me see...

Point here is that there is a HUGE difference in speed.
20 KB/s vs 600 KB/s (& packet size too; 130 vs 840).
Duplicate Cleaner being very slow performing the scan.

> slow in the 'building file list' stage

Yes, pretty sure that was the case.

Yes, slow in the 'Building File List..." stage.
(So slow, that I am not about to let it finish to see if other areas are also affected.)

This is fixed now in 3.2.7 -coming very soon.

Test on QNAP NAS:-

3.2.6
Total Time Taken: 00:03:49
9719/9719 Files Scanned (3.56 GB)

3.2.7
Total Time Taken: 00:00:47
9719/9719 Files Scanned (3.56 GB)

The savings are in the file discovery stage - a huge difference (tested several times back and forth to allow for disk caching skewing the results).

I am not seeing any improvement on my end...

NAS is 192.168.1.64

The packet speed won't change, but at the file discovery stage it is now making one trip per file rather than three - previous versions made two extra trips to fetch dates created and modified.

I don't really know what the charts I posted "mean" - hoping you will... ;-).

And while there may have been changes made between 3.2.6 & 3.2.7, they are not being realized - at least on my end, as NAS scanning is still extremely slow.

(I've sent a PM.)
