The instructions mention a number of times that you cannot see the progress using the local web app instance, you must use app.plex.tv to see the progress of the scanner.
I have 3000 album, set mine to run as a a scheduled task from midnight to 7 am, was done in a week on a 2013 i5 iMac with 8gb RAM.
Still lame I donât ever use their web interface. My local serve instance should show this info
Thanks for sharing that, it explains why it sometimes appears, as I often log into the local IP address.
Just adding to the conversation about what type of analysis would be comparable to Super Sonic and worth incorporating into Roon, BeaTunes is worth a look.
beaTunes employs sophisticated algorithms to analyze your music for metadata like tempo (BPM), key, color, segments, similarities, loudness, and acoustical fingerprints. It lets you know, whatâs in all those files!
Analysis is a stable foundation for great sounding playlists as well as tag lookup and acoustical duplicate detection.
Thanks for the tip.
I tried it and it seems to want to change my files. Maybe for the better but i donât like that very much. Have to look deeper into it.
Do you use beatunes icw Roon? Can you give some insight?
Mines finished analysing.
Sorry but James Say something and Mojave 3â keep it all Hid are about as sonically similar as a bee and a dog, Plex seems to think otherwise. Looking at what it throws up I am failing to see the excitement here . Itâs lot more eclectic mix of thatâs what you want but itâs going more off piste from my starting point than Roon radio ever does. I also donât want to listen to songs that are all the same pace which this seems to be what itâs doing track wise anyway.
I think itâs more anticipation than excitement 
. Going to be waiting a while
You need to ditch that NAS as server. Use it as NAS and use a real computer. 
I have lotâs of real computers 
(too many really). I am just using them all for other things.
The Synology Nas is plenty of powerful enough for most of what I ask for it (basically Plex movies, TV and music) and has no issues with anything else. Itâs just this process doesnât seem very optimised and I might only use it once or twice
I do actually have a Nuc 7th Gen i5 that I installed Ubuntu and Plex on, but that is now set up with HQPLAYER embedded for me to test to the iFi Stream.
I used to run mine on my QNAP but it choked for transcoding, esoecially 4k or HDR which I used away from home and family use it in other households. So swapped to Ubuntu and an i3 NuC now itâs so.much quicker to navigate and transcoding even HDR transcoding is done via the GPU without getting bothered at all.
Thatâs probably where I will end up once I have finished playing with the latest setup.
Trying not to run a data center in my study though 
Mines in the cupboard under the stairs. Now I have the USW16 and CloudKey feels less like a home network when I look in there, Need some nice cable tidying though.
Get yourself some good whisky and get Graeme round for some work. Looks like his specialist subject
Honestly, I own a license for an older version, but I havenât used the program in years and I donât recall when I originally bought it. Iâm a Roon Lifetime subscriber, so I do most of my listening via Roon or Spotify.
Only about 1 week and some time to to go 
I assume when that finishes the next 200 tracks I have added will start so that will be another day 
Not bothered with it since my responses here. Most likely wonât use it as I just donât like it as an interface and it doesnât interact with any of my hifi properly.
I understand, but I have been away for 3 days and was thinking it might be closer to completion, it analyses dog slow.
Its a quad core machine with 8GB of RAM.
Iâm going to let it finish before I decide to be disappointed though 
I think you may like what it throws up. The mixes are fine if you like what it does but I donât find them any better than standard Roon radio a few more curve balls , but I am not interested in hearing music all the same pace and rhythm which is what it seemed to be for me.
I already have Tidal for that (or YouTube and Spotify) so it is more out of interest for when I am in work and traveling. Maybe my memory of using Pandora in itâs early years has worn with age, but that used to give me great results. Maybe I am expect too much, but those songs rarely had the same pace, especially if I seeded it with 3 or 4 songs to kick it off.
Maybe that is the difference
