Avoid Nasty Surprises !!!

Major Performance issues raised

Tuning an entire month's worth of code..It can be a tedious task..

Performance??No mention in initial plans!!

Story #1:Fit it later

New Version goes live soonLets 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

Story #3:Which branch is culprit?

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

Continuous

Sustainable

Maintainable

Traceable

Efficient

Introducing Continuous performance

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.

Establishing a process

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.
