In order to improve speed performance efficiently, it is vital to find the functions with the greatest impact on performance.
As shown below, CS+ lets you tell at a glance what proportion of execution time is taken by each function. This graph shows that the func1a function accounts for the largest proportion of execution time, so revising the processing performed by func1a will probably be an efficient way to improve performance.
When performing analysis, it is vital to select the appropriate data and methods to use for analysis, in accordance with what you are analyzing. We therefore recommend that you gain a good understanding of the material in this tutorial.
