HP LoadRunner™
Industry leader for application performance validation
2 April 10, 2023
What is automated load testing?
• Replaces real users with thousands of “virtual” users
• Generates accurate, measurable and repeatable load on the system from a single point of control
• Pinpoints bottlenecks in the system

How does LoadRunner™ work?
• Record an application business process into an automated script− e.g. “Create new order” in an ecommerce web application
• Add end-user transactions, parameterize input data, add verification checkpoints
• Apply user behaviors such as network connectivity, pacing etc…

How does LoadRunner™ work?
• Design and execute load scenarios that mimic production conditions• Emulate hundreds or thousands of concurrent users from one or more locations• Gather end-to-end transaction response times
− e.g. “logon”, “select product”, “process credit card”, and total “create order” process• Collect application, network and system data across all architectural tiers and components

How does LoadRunner™ work?
• Determine if service level objectives have been met by each transaction• Pinpoints bottlenecks in the end-user, network, system and application code• Compare baselines across multiple load tests

Breadth of analysis
System: Application server CPU reached 90% at 500 users
End user: Transaction “look up account” took 17.58 seconds at 250 users
Network: London to datacenter network segment very slow
Application: J2EE method “AccountLookup” took 16 seconds; 90% of end user response time
What do you see at the end of a load test?
