    So, no solution found.
    Flac/PCM setting on filetypes makes no difference.
    Card is Samsung Evo 32GB.

    System seems quite idle while streaming from Spotify (check image).
    Connection is good (other local LMS works fine with spotty).
    So, no clue, really.

    And make sure you have decent storage media for your cache: when you're
    browsing albums LMS will have to read all the images from the cache. If
    you've got a cheap SD card, then this can be quite a bit of a bottleneck.

    Oh... this could actually be a bottleneck for Spotty, too. I think the
    helper is always storing the audio data temporarily to disk. By default
    this would be /tmp, but on some systems it's LMS' cache folder, as /tmp
    can be rather small.

    What kind of SD card are you using?

    Also make sure you enabled "high memory usage" for the database
    (unrelated to spotty).

    An update on this issue.

    I didn't realise at the time but I had moved the Cache etc to my NAS within the piCorePlayer setup.

    This obviously has the benefit of making sure that all your Prefs are saved to the NAS and allows you to easily recover from an SD card corruption but there is this trade off which I have tripped over.
    Something for other users to be aware thats all.

    iPeng is misreporting the location of the Cache etc - LMS is on piCorePlayer based Pi3 but the Cache & Prefs are on my NAS !!

    See post above.

    Actually I have realised that the piCorePlayer move Cache etc probably creates a symlink in which case iPeng is correct but it is misleading.

    Can you confirm that Settings/Information would report the same as iPeng?

    And could you move the cache back to on-device, just to be sure the pCP
    <-> NAS communication isn't the bottleneck you've been looking for?

    I will move the cache and advise but pretty sure it is the cause of the bottleneck. The Pi’s LAN is of course it’s weak point being only 100mb and the bus is shared with the USB. I can’t do the cache move today unfortunately.

    I built LMS onto some new (secondhand) hardware today.
    An HP Microserver, AMD Turion(tm) II Neo N40L Dual-Core Processor, 2 cores with 8GB RAM and a 32GB SSD i.e. a very capable machine
    OS is Vortexbox 2.4 hacked about a bit and with Logitech Media Server Version: 7.9.1 - 1521043527
    Music is still on my NAS (NFS mount) but Cache & Prefs are now on the SSD
    Ran the "Find albums with small artwork" thingy and it still borked the playback but not for anywhere near as long as on the Pi.

    @Michael.
    Does the small artwork search read the music files or just the database / Cache ?

    This is becoming rather off topic... neither Spotty nor Pi involved?

    > Does the small artwork search read the music files or just the database

    That process is super slow, as it first would query all tracks to find
    the corresponding albums, then go read all artwork files for all those
    albums to figure out the size. Then go query the album information for
    that album if the size was as requested.

    It could probably be better implemented. But it's nothing you'd run
    regularly, therefore not representative for general LMS use. Or even
    less so Spotty :-).

    FWIW: that query is poorly implemented in that it doesn't give the
    server time to "breath". LMS is basically cooperative multi-tasking: a
    long running task can tell LMS to do some streaming every now and then.
    I don't do this in that particular case. I probably should. But as I
    said it shouldn't be considered a benchmark for overall LMS performance.
