Agile India Conference 2015- Techniques to speed up build pipeline

Key principles to speed up the build pipeline
- Focus on the bottleneck- pattern : file operations related
- Divide and conquer
- Fail Fast

- Every time not required to build the jar

- Test on smaller but apt data set

- Robocupy/rsync can help in reducing the copy time as it only differncial copy.

- Use SSD instead of HDD.

- Use in memory DB-SoftPerfect Ram disk can carve disk

- Don't initialize the spring application context, it can be shared application context.

- Do CPU profiling.

- java.until.Calendar is horribly slow. Joda date library.

- Ant has fork mode. Keep forkmode=once

- Create parallel jobs

- Distribute task across multiple slaves.

Fail Fast:

- Restructure the build pipeline.

- Prioritize the test- use protest frame work.

- Incremental build vs clean build
