Memory monitor showed same readings as Activity Monitor. I don't know whether these readings are good or bad. Memory indicated by Activity Monitor is horrifying. Should i be worried? Can i somehow estimate memory used by the application once its moved to the device. The real run time memory? Thanks.

Solution

  • Memory usage as reported by Object Allocation is not very autoritative, at least according to my experience. The real deal is the real memory consumption as reported by Memory Monitor, see my question on iPhone memory consumption. Your numbers seem to be measured in Simulator, such measurement is worthless. You have to measure on the device.
