    Description

      With useCanonCache off by default, we can profit slightly from avoiding creating ExpiringCaches in the FileSystem classes by default. This avoids loading and initializing 3 classes on startup.

      It also seems the boolean flags read during startup can be made final, allowing JIT to optimize certain operations better.
