This is a project to make building the Solaris OS/Networking (ON) consolidation go faster. Hopefully, the optimizations and lessons learned through this effort can be applied to make builds go faster in general not just for ON.

Brainstorming

• Ideas
• Questions
• Issues

Discussions

• OpenSolaris discussion of making builds faster

• OpenSolaris-discuss proposal for opening a project

• Tools-discuss thread proposing project and discussion of possible build improvements

Observability

• Observing the build

Results

• Build Times

• Results from running dtrace script to analyze where most time (in seconds) spent during build (on non-debug clobber build on a SunFire X4600 with 8 dual core Opterons and 32 gig of RAM)
