Thanks for posting the link, Boris. Some notes:
- You can control the Camera Raw cache location and size with PS CS2 or Bridge by setting the Camera Raw preferences, either from Bridge or from the Camera Raw plugin itself if you have PSE instead. - On Mac OS X systems, the default Camera Raw cache directory is located at the path: ~/Library/Caches/Adobe Camera Raw - The Mac OS X path to the Preferences.xmp file if you want to edit it is ~/Library/Application Support/Adobe/CameraRaw/Defaults/ I do see a modest speed improvement in Lightroom when I set the cache size up to 20Gbytes. Happily, I have plenty of room on my startup drive so this is not a problem at all.
