Please, please, pass the thumbnail and screen preview generation to a secondary/background/lower priority thread when generating locally.
It becomes unbearable to have to wait sometimes more than 5 minutes just to make a selection, apply a filter or any other simple operation that does not require the image to be rendered!
Maybe you need a 'Generate when Idle' switch, on the preferences, so that preview generation is halted when a user is performing other tasks (like copying, renaming, reviewing, presenting, etc.). I even suggest to create a service (in Windows, at least) that could periodically scan the Bridge-registered folders and update, generate and compress the previews at least.
