5. WHY LOAD TEST YOUR APPLICATION?
Business Architects & Dev End-Users
Prevent failures on “Go-live” Validating design goals Verifying Consistent end-user
experience.
Baseline against competitors Establishing scalability patterns
and verifying capacity
requirements
Validating functional integrity
under load
Reduce cost of hardware &
software
Optimising software & hardware
configuration settings
for maximum throughput
Ensuring increased confidence in
application
 Prevents costly failures of mission-critical applications.
 Assures performance under real-world conditions.
 Locates potential problems prior deploying application in production.
 Sizing your IT components.
 Reduces infrastructure costs

6. HOW DO WE TEST FOR PERFORMANCE?
Application

7. LOAD TESTING PROCESS

8. LOADRUNNER COMPONENTS
Load Generator
 Injects load (vusers)
Recording Engine
 Record business process.
 Enhance scripts.
Administrative console
 Design & execute scenario
 Define Monitors

12. ANALYSIS

13. IDENTIFYING THE BOTTLENECK

14. DEMO: LOADRUNNER ANALYSIS
 Application: Flight reservation system (Web based)
 Business process: Logon, Search flight, book, check itinerary, Logoff
 Load testing was done for 70 users; 2-users @ every 3 seconds
Background
 SLA specific goal based on ‘Avg transaction response’ times
Analysis: Inputs
Load Criteria User Load Response times
Light Load Between 0 & 20 5-seconds or less
Average Load Between 20 & 49 10-seconds or less
Heavy Load More than 50 15-seconds or less
