Just last night I improved the startup of one of my apps in C++ which had a previously unexplainable 1 second delay by precomputing some string joins and splits at build time. I nearly cried. Thanks to the Instruments app on OSX which is seriously awesome! Startup is now instantaneous. It was also making queries slower. Queries are now also instantaneous.
