This talk was presented at VodQA Gurgaon 5th edition (22nd March 2014)

1. Continuous Performance
Testing

Avoid Nasty Surprises !!!

2. Major Performance
issues raised
Tuning an entire
month's worth of code..
It can be a tedious task..
Performance??
No mention in initial plans!!

3. New Version goes live soon
Lets check performance
Performance degraded
QA
Lets profile
our application
QA
Performance increase by 10%
But its still poor
CPU utilization is 50%
Application needs to go
Live !!!!
Alert Raised too late

last release candidate
Which branch exactly
Impacted performance

5. 
Leaving load testing until late in the development lifecycle

Inconvenience to developers in fixing performance issues

Decreased productivity

Destroyed Customer relations
Lessons Learnt

Increased development and hardware costs

6. Continuous
Sustainable
Maintainable
Traceable
Efficient
Introducing Continuous performance

7. Step One: Include performance in the requirements definition.
Step Two: Work performance testing into the development timeline.
Step Three:Conduct performance tests on a regular basis.
Step Four:Constantly monitor performance activity.

8. Step Five:Track the performance history as the application grows.
Step Six:Use that data to get a fix on the code responsible for bottlenecks.
Step Seven:Use your knowledge to efficiently tune only the code that caused
the performance problem.
