Extremely slow -Windows / 1165 series

Help & Support
#1

Hi all,

How do I go about troubleshooting an extremely slow instance of Sonarr? I have reinstalled it (and imported the backup). When I say slow- we are looking at 1-2 mins to send a nzb to Sab. I have ruled Sab out as the problem. (When I send nzbs to it through other means either Radarr or direct from indexer- it picks it up instantly).

If I tell it to grab all of one season, you may as well go for a walk, since it will take 20-30 mins just to send the links to SAB to download.

When I attempt to bring up the logs page, it indefinitely does the loading balls back and forth.

System specs:
Server 2016 Standard
96GB RAM
2x AMD Opteron 6174

This is a dedicated file server. It runs SAB, Sonarr, Radarr, PlexPy. Typically CPU usage hovers around 15-20%. Not sure if relevant, but it is also managing 1165 TV series. This used to work fine.

Any suggestions?

((Trace logs)) will show every step of the process with lots of detail including the search process and sending releases to SAB.

We’ll also need:
Sonarr version (exact version):
Mono version (if Sonarr is not running on Windows):
OS:

Thanks for the response, and sorry for the delay.

Also, it is missing a fair bit of posters… how do I tell it to redownload posters? (this was my fault during backup / restore

Fixed the posters.

Just trying to figure out the slowness now. It is to the point, that it can’t keep up with downloads over the weekends. Tends to be a few hours behind in sending the shows over.

Bump!

Still having issues :frowning:

I actually just came across something:

Rss Sync 10 minutes 15 hours ago now
Its been running for the last 15 hours.

I think the reason you’re seeing the RSS Sync take so long is due to items not being cleared out of the pending releases table, which is related to this PR: https://github.com/Sonarr/Sonarr/pull/2119 (see the last reply in the thread).

Emptying the PendingReleases table in a SQLite editor will fix up that issue until we have a proper fix in place. You can do that in a SQLite editor by opening nzbdrone.db and running DELETE * FROM PendingReleases.
