采用如下report 研究asynchronous RFC call的性能提升:

PARAMETERS: num TYPE i OBLIGATORY DEFAULT 10.
DATA:ls_line     TYPE zjerry1,
     lv_start    TYPE i,
     lv_end      TYPE i,
     lv_taskid   TYPE c LENGTH 8,
     lv_index    TYPE c LENGTH 4,
     lv_finished TYPE i,
     lv_count    TYPE i.

START-OF-SELECTION.
  PERFORM solution2.

FORM solution2.
  DELETE FROM zjerry1.

  GET RUN TIME FIELD lv_start.

  DO num TIMES.
    lv_index = sy-index.
    lv_taskid = 'Task' && lv_index.

    CALL FUNCTION 'ZINSERT' STARTING NEW TASK lv_taskid PERFORMING callback ON END OF TASK
      EXPORTING
        iv_index = CONV comm_product-product_id( sy-index ).
  ENDDO.

  WAIT UNTIL lv_finished = num.
  GET RUN TIME FIELD lv_end.

  lv_end = lv_end - lv_start.

  WRITE: / 'Solution2: ' , lv_end COLOR COL_NEGATIVE.

  SELECT COUNT( * ) INTO lv_count FROM zjerry1.

  ASSERT lv_count = num.
ENDFORM.
FORM callback USING p_task TYPE clike.
  ADD 1 TO lv_finished.
ENDFORM.

function module ZINSERTmonitor的是一个比较费时的操作，在末尾会有一个DB的insertion:

DATA: ls_line TYPE zjerry1,
        lv_cal  TYPE timestamp,
        lv_cal1 TYPE timestamp.

  GET TIME STAMP FIELD lv_cal.
  DO 10000 TIMES.
    lv_cal = lv_cal + 1.

    lv_cal = ( lv_cal * 13 ) / 12.

    DO 100 TIMES.
      GET TIME STAMP FIELD lv_cal1.

      lv_cal = lv_cal  * 13 / 17.
    ENDDO.
  ENDDO.

  ls_line-code_value = iv_index.

  INSERT zjerry1 FROM ls_line.
  ASSERT sy-subrc = 0.
  COMMIT WORK AND WAIT.

DB的结构非常简单:
