readBytesPhysical

Other cases

• case cpuUser

  CPU user space time spent for running the test

• case cpuSystem

  CPU system time spent for running the test

• case cpuTotal

  CPU total time spent for running the test (system + user)

• case wallClock

  Wall clock time for running the test

• case throughput

  Operations / second, .prefersLarger

• case peakMemoryResident

  Measure resident memory usage - sampled during runtime

• case peakMemoryResidentDelta

  Measure resident memory usage - sampled during runtime (subtracting start of benchmark baseline resident amount)

• case peakMemoryVirtual

  Measure virtual memory usage - sampled during runtime

• case mallocCountSmall

  Number of small malloc calls

• case mallocCountLarge

  Number of large malloc calls

• case mallocCountTotal

  Number of small+large mallocs

• case allocatedResidentMemory

  The amount of allocated resident memory according to the memory allocator by the application (does not include metadata overhead etc)

• case memoryLeaked

  Number of small+large mallocs - small+large frees in resident memory

• case syscalls

  Measure number of syscalls made during the test

• case contextSwitches

  Measure number of context switches made during the test

• case threads

  Sample the maximum number of threads in the process under the test (not exact)

• case threadsRunning

  Sample the maximum number of threads actually running under the test (not exact)

• case instructions

  The number instructions executed

• case objectAllocCount

  Number of object allocations (implicit retain of one) (ARC)

• case retainCount

  Number of retains (ARC)

• case releaseCount

  Number of releases (ARC)

• case retainReleaseDelta

  ABS(retains-releases) - if this is non-zero, it would typically mean the benchmark has a retain cycle (use Memory Graph Debugger to troubleshoot) or that startMeasurement/stopMeasurement aren’t used properly

• case custom(String, polarity: Polarity, useScalingFactor: Bool)

  Custom metric

• case delta

  Used internally as placeholders for formatting deltas in an easy way, please don’t use

• case deltaPercentage
