My first real experience with responsiveness goes way back to Visual C++® and MFC and the first grid I ever wrote. I was helping write a pharmacy application that had to be able to show every drug in a complex formulary. The problem was that there were 30,000 drugs, so we decided to give the appearance of responsiveness by filling the first screenful of drugs in the UI thread (in about 50 milliseconds), then using a background thread to finish filling the non-visible drugs (in about 10 seconds)
