I have a list of 220 videos in a folder. Whether scrolling a list or a grid, performance is very slow, with the UI often lagging seconds behind input. When holding ‘down’ to scroll continuous, I get a highly variable scrolling framerate — ranging from a 10 fps down to a less than 1 fps.
Files are being access over 100BASE-T ethernet, stored on a USB drive attached to an Airport Extreme.
There’s no caching or metadata loading activity ongoing during this scrolling. (On a related note though, movie thumbnails can be slow to appear after scrolling.)
Is this fixable?
