If the re-analysis is not finished it will pick up where it left off starting as 0 of X where X is the remaining un analyzed albums. For example, library of 1500, begins 0 of 1500; then if 250 gets analyzed and things are shut down, the next time it will be 0 of 1250. That is normal.
So do you mean, every time you start Roon it begins analysis again and restarts as 0 of 1500 (using the above example)?
I thought the analysing had finished (so 1500 of 1500 in your example) then reset itself after re-opening Roon. Is this also normal from a shutdown/restart? and waking from sleep?
I will try one more time and post back here to confirm.
It’s behaving itself now 
Hey Paul, did you do anything or did it just correct itself?
There was a update (build 209) to Roon not sure if that fixed the problem or Roon resetting back to zero each time that mislead me to think it was staring from scratch.
24 hours to analyze 350 files 14 000 left. This should take about a month 
Have you tried assigning more computing power (cores) to the job?
Roon Settings > Library > Background Analysis Speed
Im have the core running in server mode on a Asrock Beebox with 4gb ram. It may be a bit weak for the task. Only 2 cores.
Hi Nils, that devices Celeron is indeed probably working overtime running the heavy processing Audio Analysis Task. I would throttle background analysis while listening and then turn it up to Fast all the other times.
But, yes, this processing is slow (even on much much faster processors) and sometimes it seems like it is stuck but not really.
I have a NUC with i3 and 8 gb ram that i dont use. I think i will connect that beside my nas on the kitchen and run core with library on it. Can i use the server software on the beebox just as a player (renderer) ? (Jriver dont work)
Once you setup a Core and transfer the database to the NUC. Yes, I believe that it will function as a RoonBridge.
