I remember 5-6 yrs ago I tried to create an app using Pascal to remove cache/temporary files, fix registry errors and a few optimizations like popular "optimization/speedup" apps. I wanted to show the progress on progress bar but see what: the process just took 0.3-0.5 seconds and the progress bar is not required anymore. But I wanted to show it anyway and put random amount of wait time (sleep) between steeps. I didn't realize why the popular apps needs 3-5 minutes for the task that my simple app just needs 0.5-1 second.
