Noticing a lot of non-stop NFS traffic from Roon app

I have been noticing a lot of non-stop NFS traffic from my Roon.app on my Mac 10.10.3 to my FreeNAS 9.3 file server. The music share is automounted via NFS and seems to import new albums fine (provided I quit the Roon app while the ripping is taking place, otherwise it thinks some of the flac files are corrupt , mentioned in a previous posting).

Anyway, I would expect this NFS traffic and disk I/O due to profiling the file files and/or creating a transcoded version of the files but I see no mention of transcoding so I suspect it is re-profiling the files again and again. There is no indication of what is running in the background so I can see how close it is to finishing or what the drawback would be to just shutting down the Roon app.

My library is not huge (2.750 albums or about). It seems to mostly have been identified fine.

Other than this NFS traffic I would just like to say I love the new app but sorely miss the Control 10 functionality in my living room. I suspect I will not get the Control 10 repaired again (second time the motherboard overheats and malfunctions) and just replace it with a Tablet running the Roon app when it is released.

After the initial indexing pass, Roon goes through all of your files and decodes them to PCM to analyze for gapless playback, volume leveling, and to build those cute waveform displays that you see behind the seekbars.

For a collection of that size, analyzing the whole thing might take several days. This should be a one-time thing, though. You can adjust how aggressive we are with analysis in Settings -> Setup -> Audio Analysis Speed. We don’t recommend turning it off, but that’s possible too.

Personally, I like to run it on “fast” so it finishes quicker, even though that means using more resources while it’s working. “Normal” is artificially slowed down to use approximately 1/3 of a CPU core in order to minimize disruption/heat/fan noise. “Fast” tries to use 1 full CPU core for analysis, assuming your storage devices and network can keep up.
