Slow and Sluggish on Raspberry Pi
#1
Sad 
Hi I have the Open Elec version of XBMC installed on a 16gb class 10 SD card on my pi with a 2tb hard drive attached with 250+ films going through 500mbps home plugs.
Ok the problem is that going through the menu's and cycling through my films it's very very slow and sluggish, is there a setting I have wrong or is it something else.

Please please help it's driving me mad..

Thankyou. Confused

Is the hard drive attached by a powered hub? Is the Rpi overclocked? Instead of installing Open Elec to an SD card, try installing to a USB pendrive. Raspbmc has this option with the windows installer. Is your power-supply giving enough power the Rpi?

My Pi is very sluggish as well after I first enter the 'Movies' selection or after I exit 'Information' for a movie. I have turned on debug, and what is occuring is the following:

DEBUG: DoWork - trying to extract filestream details from video file smb://pcdoctorg/movies/Zodiac DVD (2007)/Zodiac (2007).iso

The above line appears for many of my movies in my large movie database. I don't know if this is maybe what you are seeing, but it definitely is impacting my performance until it goes through the list of movies. I would suggest turning on debug to maybe get some more informaiton as to what is impacting your system.

So it appers that xbmc is trying to extract filestream details for many movies from my large move database everytime I enter or reenter the 'Movies' selection.

I don't know if there is a reason for this or how to correct this. Hopefully someone can address this issue.

stuConners: Hi it's plugged in directly into the pi usb port an I am using the 12v 2amp psu aswell that came with the pie. My 2tb external drive is powered by mains it's not a portable drive.
It's not overclocked it's completely standard as I am a newbie to the pi. Where can I get Raspbmc from? Thanks.

Nope, you'll only lose the auto generated thumbs whenever you have a file that doesn't have an actual set thumb (the ones where it just takes a raw screen shot and uses it as a thumb). Anything scanned into the library will still work normally.

When you go to movies do you see the total duration at the bottom right of the screen? That's what's slowing you down until it is calculated. You could probably remove it by editing some xml file somewhere, I haven't been bothered to look.

From the wiki: "Extract thumbnail and video information - When enabled, XBMC will extract thumbnails from videos that have no thumb in the library and information such as codecs and aspect ratio to display in Library Mode."

Loosing the video information is not nice at all :S

Noticed that lately the calculation seem much faster... it could be the OC kicking in thou Smile

I don't think that's the same as the duration calculation, thumbnails/codec info should only be extracted once. The total duration seems to update every time you open/return to the screen, If it was static and only updated on scans or once per session it wouldn't be so annoying

There should be a skin option to disable it on the RPi.

btw if you want to remove it manually look in includes.xml

The only information you lose is a little media flag that says something like "H.264" or "AAC". It's a trade off; if you want better performance for core features then you have to turn off extra features. It's no different than if someone used a heavy-feature skin vs a light feature skin on the Pi.

Slightly off topic, but can't you have the "H.264" and "AAC" information stored in the NFO file, eliminating the "trade-off"?

In the build from the 19th it appears that the total duration in the movie library doesn't update every time you open the page. whoever fixed/changed this Thank You
