When I used Instruments tool to monitor my memory usage, I found a process named DTMobileIS use about 40% of real memory, and then there were not enough memory for my app so it crashed. I am curious about this DTMobileIS means for. Does anyone know about it?
Edit:
It seems like DT is the prefix of Debug Tool. And according to this link, IS sounds like the abbreviation of Instruments.
DTMobileIS- which I believe is the Mobile Instruments Data Server that provides info to instruments window on your Mac. I’m on the hairy edge of performance so I definitely notice the extra 7-10% CPU boost when not using instruments! It eats about 1.5-2.0MB of your precious memory while running the Activity Monitor.
debugserver- which handles console outputs, breakpoints, etc. not a big CPU user, but it is currently consuming 1.24MB in the window I’m watching right now.
So outside of a debugging/instruments environment you should have at least 3MB more memory available, and up to 10% more CPU time available according to my current readings
