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:
如果在report 里直接调用ZINSERT, response time为4.493 seconds.
如果在DO 2 TIMES里调用两次ZINSERT, 两次function module call是依次执行的，response time为8.493 seconds
如果用report 以参数2 以异步的方式调用ZINSERT 2次，report 本身的response time为3.074 seconds:
number = 3:
number = 5:
