In order to avoid unnecessary repeated routine code to measure performance such as below:
" get timestamp1
" run the method whose performance you want to measure
" get timestamp2
" duration = timestamp2 - timestamp1
I write this small tool in ER9/001.
An example of performance comparison requirement
Suppose I have written a class ZCL_CRM_CODEPLOY_DATA_TOOL which has two methods:
- SELECT_FROM_CDS_VIEW: read data from table ZCOMM_PRODUCT, which is redirected to a CDS view
- SELECT_FROM_ZCOMM_PRODUCT2: read data from table ZCOMM_PRODUCT2 as usual In order to avoid unnecessary repeated routine code to measure performance such as below:
" get timestamp1
" run the method whose performance you want to measure
" get timestamp2
" duration = timestamp2 - timestamp1
I write this small tool in ER9/001.
How to use it
Suppose I have written a class ZCL_CRM_CODEPLOY_DATA_TOOL which has two methods:
- SELECT_FROM_CDS_VIEW: read data from table ZCOMM_PRODUCT, which is redirected to a CDS view
- SELECT_FROM_ZCOMM_PRODUCT2: read data from table ZCOMM_PRODUCT2 as usual
And I would like to compare the performance of these two approaches. Now I do not need to write routine code to execute the method and measure the performance. Instead just run report ZCO_PERFORMANCE_TEST in ER9/001:
Run the report, it will execute the methods for you and display duration of each method execution ( unit: microsecond )
