My Test was with USB-Stick!

Did you added a heatsink on top of the ram before overclocking.

Is there any reason to alter rsize and wsize with the newly added readbufferfactor? Im currently on a wired network so im not concerned with dropping packets so would larger packets mean increased performance? I personally noticed an increase in network performance switching to udp from tcp. Which would you suggest?
sudo mount 192.168.4.9:/Public -o _netdev,nfsvers=3,rw,intr,noatime,rsize=32768,wsize=32768,nolock,async,proto=udp /home/pi/dell

Limited overclock may be down to the specific processor. It is often down to the power supply.
More overclock=>more power required=>more voltage drop from a poor supply.
It may be worth measuring the voltage when overclocked and under load (e.g. scrolling though views):

or just try any other power supplies (and power supply cables) you have around.

I don't think there will be any problems with performance, but I'm more nervous about memory usage.
(2013-09-29, 20:35)MilhouseVH Wrote: Setting <fanartres> to 1080 should result in more-or-less original resolution fanart, shouldn't it? (It actually results in 1920x1088 artwork, is that slightly unusual height anything to worry about?)Yes, 1080 is actually an inconvenient value. Videos are encoded with a height of 1088, and 8 pixels are cropped (as macroblocks are typically 16x16).

Perhaps keep 5 seconds for 720 (or less), and use a lower (faster) value for >720, unless there's a performance downside of course.

Yes, when tracking down the texture leak bug (https://github.com/xbmc/xbmc/pull/3331) I set the timeout to zero, and didn't see much change.
Change the 5000 to 0 (or something else) is you want to test it:
https://github.com/xbmc/xbmc/blob/master....cpp#L5002
I guess it only helps when you backtrack. i.e. scroll too far and then go back (although one row off each end of screen is cached anyway).
(2013-10-01, 00:04)MilhouseVH Wrote: Thanks. I'll re-cache my fanart at 1080 and see if 5 seconds is a problem (over NFS, still waiting for the USB3 memory stick). I'll then use a delay of 0 and see if I notice any difference. One thing that occurs to me is that, if GPU memory is limited, couldn't textures simply be evicted from GPU RAM as required? Then you could have a longer lazy eviction time, but also evict on demand if/when required to free up RAM.
