MaxMemoryUsed

MaxMemoryUsed[]
gives the maximum number of bytes used to store all data for the current Mathematica session.
  • On most computer systems, MaxMemoryUsed[] will give results close to those obtained from external process status requests.
  • MaxMemoryUsed[] will not typically account for code space, stack space or the effects of heap fragmentation.
