The implementation still uses much of your original code (especially for downloading and caching the icons), but I did move a lot of of it to a “SFHFFaviconCache” class that implements a memory as well as a disk cache and only accesses the disk if the icon isn’t in the memory cache. I also improved the 2D drawing performance, which was the real killer (pre-sized the images and turned off caching for the in-memory icon images).

Thanks again for all your work!
