Enabling the Deep Profile option recompiles our scripts with a much deeper level of instrumentation, allowing it to measure each and every invoked method. This causes a significantly greater instrumentation cost during runtime than normal, and uses substantially more memory since data is being collected for the entire callstack at runtime. As a consequence, deep profiling may not even be possible in large projects, as Unity may run out of memory before testing even begins, or the application may run so slowly as to make the test pointless.
