My site just migrated from FB Build 1047 to FB Build 1272. One byproduct is that Delete Folder action used to be instantanous, now it takes over 20 minutes. That's a significant increase in the overall build time. The folder is quite large 60GB, 170K files, 12K folders. My guess is this came about becuase of the enhancement described here. The "old" Folder Delete action implementation never seemed to cause me any issues. Is it possible to make the sub-folder delete latency an option? Or am I missing something important?

The delay was put in due to random issue with vista thinking folders cannot be deleted, the api call fails but if called again after a short delay it works fine. There is no an option to turn this delay on, it is off by default. This test build has the change :
