Possible to make scrolling through a big library faster?
#1
I have a huge music collection, and scrolling down from A to Z in Transparency! takes a long time. It scrolls really fast a couple of seconds, then it halts, continues on really fast, halts etc... It looks to me like it may be trying to load the fanart prematurely, and this may be slowing down the scrolling ? I get the exact same slow scrolling if I try the supposedly faster right slidebar scrolling. Is there anyway I could improve this, maybe by setting a delay time for when Transparency! tries to load the fanart ?
I am running Xbmc Live 9.11 on a Asrock ION 330.
Any proposals on this is highly appreciated - thanks!

Can't you select the scrollbar and scroll like that? That works pretty nicely for me at least. Or page down. (might scroll just as fast, not sure to be honest)

You can select the scroll bar by pressing "right" when you are in the library mode Smile (I guess this is how you should be doing if you're using a remote)

I use page up/down and it moves very fast...sometimes too fast.

And I have over 500 artists in my library.

I get the same semi-slow scrolling results both with the scrollbar and page down. I guess it's because I am running on an ION processor (Asrock ION 330). The processor on this machine is quite slow. I suspect that the scrolling is slowed down by the processor just enough to let the fanart loading start every now and then --> resulting in pauses when scrolling...

I'll let you know once I get home - got an Ion 330HT-BD waiting for me Big Grin
It works fine on my both my desktop and laptop though. But I guess i7/regular dual core makes quite the difference.

500 is still artists a relativity small library. People with upwards of 5-10k artists may see other issues . I have ~15k artists in 2.5tb of flac/mp3, and notice a considerable lag in my install.

That IS impressive. Eek My collection is only about 150GB of mp3. The 500 doesn't include compilation artist that might appear only once throughout the collection, though. Only those that I've actually created folders for with the structure 'Artist\Album\song.mp3'. I'm not sure in library mode how many artists actually show up. I'm guessing a couple thousand. I can see how having a much larger collection would cause issues.

all fanart is loaded in a background thread, meaning it won't slow down browsing through your collection.
artist/album thumbs are not always loaded in the background (depends on the viewmode you're using). so if your artist/album thumbs are big (in terms of filesize) you may experience some delay.


when browsing your collection by artist, you should be able to scroll fast in these views:
thumbnail / media info / fanart

and these views will be slower (no background loading for thumbs):
coverflow / full list / list

I browse by Artist, and use the fanart view:
I have performed more testing and it turns out that it is the 'Animated Background - Multi Image' which is causing the poor performance. I have obscure artists with one 1-2 songs in my collection, and I don't have any fanart for these, so the default Background Multi Image' kicks in and destroys scrolling performance. If I turn off the Background - Multi Image, performance is OK again. The Background Multi image is set to diplay high quality images of my favorite artists, so I am not very keen on turning it off...
I guess it is not possible to somehow delay starting the Background multi image loading in order to improve scolling performance ?

thanks for clearing up this matter. it's indeed not possible to delay the multi images.

but maybe you'll see some improvement if you disable them during scrolling...
in MyMusicNav.xml change this line:
Code:
<visible>Skin.HasSetting(Enable_Custom_Back_Music) + IsEmpty(ListItem.Property(Fanart_Image)) + IsEmpty(Fanart.Image)</visible>
to:
Code:
<visible>[b]!Container.Scrolling + [/b]Skin.HasSetting(Enable_Custom_Back_Music) + IsEmpty(ListItem.Property(Fanart_Image)) + IsEmpty(Fanart.Image)</visible>

Ahhh - much better. Scrolling with the Scrollbar is now really fast Big Grin
As long as I am using the scrollbar I am now able to navigate my collection with ease!
When I scroll not using the scrollbar (artist by artist), this is still a bit slow and jerky. Is there a delay setting I can play around with in order to optimize this ?
Thanks - this fix raised the usability factor for me a lot!

Best Regards,
Thomas

Thanks - I can live with that. Usability is now excellent with the changes you proposed earlier. I just need to get used to using the scrollbar more frequently.
Since it's the end of the year, I'd like to take to thank you for all the excellent support you have provided in 2009, and wish you a HAPPY NEW YEAR!
Regards,
Thomas.
