Performance testing is a type of non-functional testing used to identify a system's response time, throughput, reliability, and scalability under given load conditions. It helps understand how a system will behave under extreme loads, identifies constraints, and which parts may misbehave in real-time. There are different types including baseline, benchmark, load, stress, endurance, and volume testing. JMeter is an open source tool commonly used for performance testing as it can simulate heavy loads and provide instant visual feedback. Key challenges include accurately simulating high user loads, implementing real-life usage scenarios, accounting for network latency, testing certain systems like chat servers, and reducing the time needed for metrics collection and report analysis.

Performance Testing
Non-functional testing.
To identify the response-time,
throughput, reliability and scalability of
the system under the given load
condition.

3. 2
Why Performance Testing?
To understand behavior of the system
under extreme load conditions.
To understand what are all constraints of
the system.
What part of the system going to
misbehave in real time?

Performance Testing Types
Baseline Testing
Benchmark Testing
Load Testing
Stress Testing
Endurance Testing
Volume Testing

5. 4
Jmeter – Software of choice
Open source desktop/server application.
Designed for performance testing.
Simulate heavy load.
Gives instant visual feedback.
Distributed Testing.
Various protocols - HTTP, FTP, JDBC, JMS,
LDAP, SOAP

6. 5
Challenges in Load Testing
Simulation of more users load.
To implement real life scenarios.
To get real life network latency.
Load testing of Chat Server, for example
eJabberD.
To reduce time in performance metrics
collection and analyzing report.
