Description

Statistics for the PersistenceManager impl that cover:

• bundle cache access count,
• bundle cache miss count,
• bundle cache miss avg duration (this avg includes the penalty of having to load from the underlying storage / can be interpreted as avg read latency as there is no cache involved)
• bundle writes per second

What it doesn't cover is :

• number of bundles
• size of workspace
  as these are values that are expensive to compute on demand, and caching them would imply being able to store the values (which is not possible currently).
