Library scanning speed.

Library scanning speed.
Hey.

I have been running XBMC on my 2nd Gen Apple T.V for a while now and its been working pretty well but I had recently decided to play around with it on the Raspberry Pi.

Thing is, when scanning my library of 500ish movies into XBMC The Raspberry Pi is REALLY slow when compared to the Apple T.v.
The Apple TV can scan the whole Library in the time it takes the Raspberry Pi to get upto the B's.

Now I realise the Apple TV has a faster processor (1GHz vs 835MHz) but the Pi has 512MB of ram where as the Apple Tv only has 256MB...

The Apple TV has its SSD Drive, is that enough to make it SO much faster than the Pi (I'm currently using a Class4 SD Card)?

The Apple TV is also running Eden and the Pi is running the latest nightly build.

I have all the .nfos stored with the movies so XBMC should be Downloading from the internet at all.


Are there any tips for speeding up a Library scan? As everything else works great.
I even tested the Pi with an uncompressed Blu Ray disk and even though it still had to buffer ever 30 seconds or so it played much better than the Apple Tv.

RE: Library scanning speed.
Class 4 card will slow you a lot. I use a MySql central database so I don't normally scan with the PI as I can scan on a PC and it updates the database for all clients. Overclock will also help. A fast usb install will probably make the biggest improvement.

RE: Library scanning speed.
So a Class 4 SD Card is enough to slow the Pi down so the scan takes around 8 hours where as the Apple T.V can do it in under 1 hour?

RE: Library scanning speed.
Probably not but class 4 vs class 10 will make a significant difference. A good usb stick will blow them both away, there is a huge difference in usb stick speeds, a usb 3 stick should be pretty fast even though it's running on usb 2. You can check/compare speeds with Usbdeview

RE: Library scanning speed.
Is there a chance Eden and Frodo are doing their scraping differently?
I have used Media Companion to DL all the fan art, posters and info before hand.

I have also turned off "Download actor thumbnails when adding to library" which seems to have speed things up a little bit...

They did change/improve the way thumbnails are handled, this may slow it some http://wiki.xbmc.org/index.php?title=Thumbnails/Cache

That could be it... More writing to the SD card? Image processing and such?
I'm not willing to install Frodo on the Apple TV when Eden is working just fine.

At least once the initial scan has been done it wont take forever when a new movie is added.

Thanks.

RE: Library scanning speed.
Scrape your library in XBMC Mac/Win/Linux and export the library into separated files, this way the RPi doesn't go fetching from the inet, it will fetch the data from the exported files... keep the actor thumbnails off Smile

Yes, OC will make things snapier as well as a fast SD card/USB drive.

* Patriot Supersonic Boost XT 16GB USB 3.0 Flash Drive
* Energizer Charger 5V/1000mA

* ARM@1000/CORE@500/SDRAM@600/OV@6

How would you go about setting up the central mysql library? Is there a tutorial I can follow please?
Thanks,
