Introduction
• Enterprises are moving towards Agile
– Improved Quality
– Midcourse corrections
– Customer satisfaction
– Quicker time-to-market
– Competition

Traditional approach to Performance
Engineering
• Waterfall model
• Afterthought in SDLC
• Reactive approach
• Insufficient time – testing, tuning, optimization
and forecasting
• Adverse system performance
• Business losses

Testing Challenges in Agile
• Time boxed sprints
– Shorter time to test
• Test Environment
– H/w infrastructure
– Test Data
• Customer expectations
• Frequent changes
• Delivery pressures
• Defining performance user stories

Performance Planning
• Define
performance
requirements
– User
– System
• Performance
test strategy
• Workload analysis
• Tool selection
• Test data

Sprint Execution
• Performance centric
development
• Scripting and
Execution
• Performance unit
testing
• Continuous
Performance
Management
• Bottleneck
Identification

Performance Centric Development
• Technology evaluation
• Architecture and Design Review
• Prototyping
• Deployment and Production monitoring

Performance Unit Testing
• Unit tests as performance tests
• Performance Evaluation
– Code Level
– Single user performance
• Automated unit testing
– ANT, Maven
• Tools
– Junit, junitperf,TestNG, Solex,TPTP, p-unit

Performance Unit Testing

Continuous Performance Management
• Integrate test execution
& Continuous
Integration
• Component level
performance
• Automated result
analysis
– Alerts and
Notifications
• Performance

Continuous Performance Management

Bottleneck Identification
• Using Diagnostic tools
• Profiling
– Code
– Database
• System tuning
– Thread pool
– Connection pool
– JVM
– Queries
• Tools
– Yourkit, Jprofiler, visualVM,
jConsole,AWR, SQL
profiler, GC Analyzer,
Glassbox, jwebApp, Jamon

Hardening Sprint
• Dedicated sprint for performance testing
• End-to-end performance testing
• Stress andVolume testing
• Endurance, Reliability, Fail over testing
• Production monitoring
– Nagios, Zabbix,Wily, Dynatrace,AppDynamics
• Performance certification

Bill Payment Solutions
Impetus Contributions
• Defined and established Performance
engineering process in Scrum
• Defined performance tasks in product
backlog
• Performance benchmarking for critical
web services
• Defined optimal set of JVM parameters
for maximum throughput
• Recommended optimum hardware
based on expected user base
• Automated monitoring utilities to debug
performance issues
The Challenge
• Scrum development cycle
• Identify performance bottlenecks
during the development
• Identify hardware requirements for
deployment of new release
• Define optimized set of parameters for
JVM
• Benchmark and tune the individual
web services
Benefits Realized
• In time release with zero performance issues
• Cost savings due to early identification and resolution of performance issues
