Hi, I have a macbook pro that I'm using mainly for my day to day activities and certain other tasks. But I would love to install xcode on my computer to start a new line of work only if xcode would not decrease my computer's performance in any way (when its not running, of course!). All I need to know is, does it add any more weight to the booting process? Or does it automatically load any components even if xcode is not loaded (during the boot up etc)? Or would it clutter my HDD space by creating a lot of folders here and there and spreading it's files all over the disk? Thanks in advance.
