Can I speed up sonic analysis

Plex Media Server
1

Is there anything I can do to speed up sonic analysis…I have a 6 core amd 16 gigs ram and been doing analysis starting Saturday 2075 albums running 24/7 and only at 1848 left …what gives.

I am in the same boat… I have 22K left… SIGH. Feel like this has been going for like 4 days or so. This is running on a Qnap with a Celeron® J3455 quad-core 1.5 GHz processor. I did upgrade to 16GB from 2… so I think that is helping but the process is taking a long time.

As for speeding it up, I can’t really answer that. However, I think Plex can do some things in the next release to (ACT) like it is moving faster.

  1. Set like a 100 to 500 album limit that it will process, complete and allow us to view this data. I should not have to wait the entire time of processing 2075 or 25K albums to see some of this data.

  2. Already heard rumors this is coming but skip bad files and continue on. This would be really sad to get very close to being done and then all the sudden you have a bad file and you have to start all over. This is where the 100 album thing would come in handy so at least some data would be in there.

I am also looking for ways to speed this up.

More cores, faster cores. That’s the only way.

  1. I tend to agree, but you would not get very good results until a majority of the library was done anyway.
  2. it should already skip bad files, but if you can identify any which are not being skipped, I’m sure the team would like examples. The progress is stored, so restarting server etc should not cause any problems.

I’m running BSD so haven’t had the chance to use it. If you are using Linux have you tried ‘renice’ on the process?

I’ve been stuck at 1314 albums processing since the feature launched, and Plex is utilizing effectively zero CPU power at idle, even during the “scheduled tasks” period. Is there any way to kick-start the actual processing, or at least look into the logs to see what the holdup is?

edit: the server is running on an AMD R9 3900X w/ 16gb RAM, so power shouldn’t be an issue - I expected to be able to crank through the analysis, but yeah, not so much.

further edit: I turned off sonic analysis for my music library, restarted the server, and re-enabled sonic analysis, which seemed to kick-start the process. However, the number does not advance, and I have the same two lines repeatedly showing in the console with different process numbers:

[MusicAnalysis] SQLITE3:0x82448d2d, 1, no such column: blob_type in “select id from blobs where linked_type=? and linked_id=? and blob_type=?”
[MusicAnalysis] Exception inside transaction (inside=1) (…\Library\BlobDatabase.cpp:65): sqlite3_statement_backend::prepare: no such column: blob_type for SQL: select id from blobs where linked_type=? and linked_id=? and blob_type=?
