Lion's Share Garbage Collection Report

Average allocation rates are shown as the solid line. 20% to 80% of results are within the dark region, all results within the light region. If the application being studied is incredibly predictable, you might just see a single line (that just means all the runs had an identical garbage collection profile). Remember that runs may have different lifetimes.

Time spent paused doing garbage collection. Full GC and New Generation only shown separately (but note that new generation collectors can still follow new objects into dead old gen roots).
