Building Systems from Components

Efficiency?

•Ensemble stacks have many layers, improving clarity, but inefficient.

•5 optimization techniques:

1.Avoiding (in-line) garbage collection

2.Avoiding marshaling

3.Delaying non-critical message processing

4.Identifying common paths

5.Header compression


	First three techniques independent of layering. Last two beyond capabilities of compiler optimizations, and has involved hand-optimization or significant annotation of code. This is a difficult and error-prone process.
