title: What are ways of improving build/compile time?
body: <p>I am using Visual Studio, and it seems that getting rid of unused references and using statements speeds up my build time on larger projects. Are there other known ways of speeding up build time. What about for other languages and build environments?</p>
  
  <p>What is typically the bottleneck during build/compile? Disk, CPU, Memory?</p>
  
  <p>What is a list of/are good references for distributed builds?</p>
