- * BIFs for benchmarking. These only do useful things if
- * __BENCHMARK__ is defined in beam/benchmark.h. For documentation
- * about how to add new counters or maintain the existing counters,
- * see benchmark.h.
- *
- * If benchmarking is not enabled all BIFs will return false. If the
- * required benchmark feature is not enabled, the counter will remain
- * zero.
- *
- * process_info/0 -> { Number of live processes,
- * Processes spawned in total }
- *
- * Live processes are increased when a new process is created, and
- * decreased when a process dies. Processes spawned is increased
- * when a process is created.
- *
- *
- * process_info_clear/0 -> true
- *
- * Will reset the processes spawned-counters to zero. If this is
- * done at some improper time, live processes may become a negative
- * value. This is not a problem in itself, just as long as you know
- * about it.
- *
- *
- * message_info/0 -> { Messages sent,
- * Messages copied,
- * Ego messages (sender = receiver),
- * Words sent,
- * Words copied,
- * Words preallocated }
- *
- * Counting the words sent in a shared heap system will affect
- * runtime performance since it means that we have to calculate the
- * size of the mesage. With private heaps, this is done anyway and
- * will not affect performance.
- *
- *
- * message_info_clear/0 -> true
- *
- * Reset the message counters to zero.
- *
- *
- * message_sizes/0 -> true
- *
- * Displays a text-mode bar diagram with message sizes. There are no
- * guaranties that this is printed in a way the Erlang system is
- * supposed to print things.
- *
- *
- * gc_info/0 -> { Minor collections,
- * Major collections,
- * Used heap,
- * Allocated heap,
- * Max used heap,
- * Max allocated heap }
- *
- * Information about private heap garbage collections. Number of
- * minor and major collections, how much heap is used and allocated
- * and how much heap has been in use and allocated at most since the
- * counters were reset.
- *
- *
- * shared_gc_info/0 -> { Minor collections of the shared heap,
- * Major collections of the shared heap,
- * Used shared heap,
- * Allocated shared heap,
- * Max used shared heap,
- * Max allocated shared heap }
- *
- * The same as above, but for the shared heap / message area. Note,
- * that in a shared heap system the max used heap and max allocated
- * heap are mostly the same, since the heap allways is filled before
- * a garbage collection, and most garbage collections do not enlarge
- * the heap. The private heap numbers are much more interesting.
- *
- *
- * incremental_gc_info/0 -> { Complete minor GC cycles,
- * Complete major GC cycles,
- * Minor GC stages,
- * Major GC stages }
- *
- *
- * gc_info_clear/0 -> true
- *
- * Reset counters for both private and shared garbage collection.
- *
- *
- * BM Timers
- * ---------
- *
- * All timers returns tuples of the kind: { Minutes, Seconds, Milliseconds }
- * except for the max times in garbage collection where times are normally
- * small. The tuple is therefor: { Seconds, Milliseconds, Microseconds }
- *
- * system_timer/0 -> Mutator time
- *
- * This timer is not a real-time clock, it only runs when a process
- * is scheduled to run. You can not find out the accual time a
- * program has taken to run using this timer.
- *
- *
- * system_timer_clear/0 -> true
- *
- * Reset system timer to zero.
- *
- *
- * send_timer/0 -> { Send time,
- * Copy time,
- * Size time }
- *
- * Time spent in sending messages. The copy time and size time are
- * only active if the copying is needed in send. Copying of data
- * into ETS-tables etc is not timed with this timer.
- *
- *
- * send_timer_clear/0 -> true
- *
- * Reset send timers to zero.
- *
- *
- * gc_timer/0 -> { Time in minor collection,
- * Time in major collection,
- * Max time in minor collection (�s),
- * Max time in major collection (�s) }
- *
- * Total time spent in garbage collection of the private heaps. The
- * max times are for one separate collection.
- *
