Thanks for this. It looks like MinimServer is spending a lot of time scanning @eaDir directories. These are created automatically by Synology DSM within your music library and they contain album art images extracted from your music files. I have made a change in update 85 (now available) to prevent MinimServer from scanning these directories and this should reduce your rescan times.

Excellent, thanks Simon. I wonder is it the Synology Audiostation software that creates these ? Presumably redundant as I already have folder.jpg in each folder created using dbPoweramp

Can confirm that this update has made a huge difference !

Hi Simon,

I am facing the same issue. It takes around 15 minutes to do a rescan.

Have attached my log file. (Had to split it in two due to size restrictions).

Are you able to take a quick look, please?

Many thanks

Kind regards,
Peter

PS. I am aware that I have a playlist which creates some error entries ...

Now part two of the log file ....

It looks like you have set the startupScan property to 'full'. This prevents MinimServer from using its cache file, which means the contents of all your audio files are being read and processed every time you do a rescan. You will get much better rescan performance if you set the startupScan property to its default value of 'true'. See this section for details of how this works.

Hi Simon,

You were right. The startupScan property was set to "full". So I changed that to "true", and now a Rescan takes around 12 minutes.

What I did was:
1) change the startupScan property to "true"
2) performed a Restart of MimimServer from within the Synology Package Center - which also took around 12 minutes
3) copied 14 updated files to the NAS, i.e. replaced 14 old ones with the 14 updated ones
4) performed a Rescan from the MinimWatch right-click-on-icon menu

Are there any other properties that I need to set?

Many thanks

Kind regards,
Peter

This still seems a bit slower than I would expect. How many albums/tracks do you have? What model of NAS do you have? What HDD(s) are in the NAS?

Hi Simon,

I have:

• 36,481 tracks consolidated into 3,041 albums
• The NAS is a Synology DiskStation DS214se
• HDDs are 2 x Western Digital 2TB Red WD20EFRX SATA 3

The DS214se has a very slow processor and this is probably the reason for the fairly long rescan time. I don't think there are any other property settings you could change to make rescanning faster.

Thank you Simon,

So if I "upgrade", e.g. to a model with a Dual Core 1.3 GHz CPU, that should be noticeable in terms of performance?

How important is the system memory?

Many thanks

Kind regards,
Peter
