• I've asked for help in the Truffle Gitter before filing this issue.

Issue

Truffle could be faster. We need to profile it, find bottlenecks and implement some caching.

• truffle version takes 4s on my computer
• truffle test with solidity tests doesn't cache compiled contracts and artifacts and rebuilds them on every run

Steps to Reproduce

• run truffle version
• run truffle tests with solidity tests

Expected Behavior

• I expect time for truffle version to be negligible
• I expect second test run to be faster than the first one and use precompiled contracts or only recompile the changed ones.
  • Maybe use a temp directory
  • Maybe have a directory inside of a project ignored in a generated .gitignore

Actual Results
