Execution testing is used to determine whether the system can meet the specific performance criteria. It INCLUDES

1. Verifying the optimum use of hardware and software. 
2. Determining the response time to online USER requests. 
3. Determining transaction processing turnaround time. 

Execution testing can be done in any phase of SDLC. It can evaluate a single aspect of the system like a critical routine in the system. We can use hardware and software monitors or creating quick and dirty programs to evaluate the approximate performance of a completed system. This testing may be EXECUTED onsite or offsite for the performance of the test. It may be noted that the earlier the technique is used, the HIGHER is the assurance that the completed application will meet the performance criteria.
