Final answer:
You would typically use resultCount to calculate performance, as it directly reflects the output. ScanCount measures the amount of work performed.
Step-by-step explanation:
To calculate performance, you would typically use resultCount. ResultCount refers to the number of items or records produced as a result of a search or operation. It is commonly used in software and database performance evaluations.
On the other hand, scanCount refers to the number of database items scanned or examined during a search or operation. It is used to measure the amount of work performed by a search or operation.
In most performance evaluation scenarios, resultCount is a better metric to gauge efficiency and effectiveness, as it directly reflects the output of the search or operation.
