Insight Into Slow Indexing

Recommended Posts

I have been struggling for a couple of months now trying to get 4 QNAP NAS drives syncing about 2TB of data, all of which had been pre-loaded.

 

Indexing has been a nightmare and never seemed to move forward. For weeks and weeks.

 

Finally, I found that if I stopped btsync on all but one NAS at a time, it would successfully sync all 2TB in about 12hrs.  Note, btsync had to be *stopped* completely (i.e. I would ssh in and run ./btsync.sh stop --- not just paused in the UI.

 

Pausing seems to stop the transfer of files (?) but not the back-and-forth communication about the files and somehow, it seems that interferes with the indexing sufficiently to grind it completely to a halt.

This is definitely an issue, and broader than just the NAS based clients.

 

Start-up indexing of large folders is miles quicker to complete on OS X with the client paused.

I don't know if your issue is being resolved, but it's december 2017 and I still have slow indexing issues. Indexing already took 2 days, and seems to be getting slower by the hour.
I use a 8TB external HDD with read/write speeds of about 100MB/s. And this is not on a NAS, but on a Laptop. So like linenoise stated, it's not only an issue on a NAS.
Also I use the exFAT filesystem, in case this minds.
