5. Disable RSS
XBMC comes with a nice RSS news scroller on the homescreen.
This is nice but it does affect the performance quite a bit. So I strongly suggest disabling RSS feeds on Raspberry Pi. I would rather devote that resources to improve my XBMC media center performance.
6. Disable Weather Info
Displaying weather info on homescreen uses resources as XBMC tries to connect to servers and update weather information. Therefore, I recommend not displaying weather info on homescreen.
7. Disable Fanart
Well fanarts are nice and many may prefer to show them, especially if you are showing off your media center to a friend who has no clue about XBMC or any relevant topic. But after the initial love you just want pure performance. So I suggest you consider disabling fanart.

8. Disable Recent Videos and Albums
Displaying recent videos and albums on the homescreen is another feature that might adversely affect XBMC performance on Raspberry Pi. Moving through homescreen items can stutter. So I suggest, you disable displaying thumbnails of recent videos and albums on the homescreen.
9. Choose a Simple Skin
The Skin you use has probably the greatest impact on the performance of Raspberry Pi media center. In my other post, I presented a few alternatives to the default Confluence skin on Raspberry Pi. Check them out. If you are quite content with the default skin, my recommendation is to just stick with it (I did) as seems to perform well on Raspberry Pi’s low-end hardware. If you do not like the Confluence skin, then I suggest Quartz or even Amber skins.
10. Decrease Resolution
This, I am not entirely sure if it has a noticeable impact on performance. But displaying high resolution graphics does drain the resources. So if your display screen is small enough, I suggest reducing the display resolution from 1080p to 720p.
Of course, in the end the choice is yours. You have to decide which features you cannot let go of and which features you can afford to lose. Practically, though if you disable all the above features all you would have is a plain vanilla media center and most people won’t like that. In my experience, overclocking has the most impact on XBMC performance of Raspberry Pi and you may even get by with not disabling any thing.
