The profiled code ran for {{TotalTime}}ms. Of this, {{GCOverheadTime}}ms were spent on garbage collection (that's {{GCOverheadTimePercent}}%).
The dynamic optimizer was active for {{SpeshTimePercent}}% of the program's run time.

The profiled code did {{GCRuns}} garbage collections. There were {{FullGCRuns}} full collections involving the entire heap.
The average nursery collection time was {{NurseryAverage}}ms. The average full collection time was {{FullAverage}}ms. On average, {{AverageParticipants}} threads participated in GC.
Of {{OptimizedFrames}} specialized or JIT-compiled frames, there were {{DeoptOnes}} deoptimizations (that's {{DeoptOnePercent}}% of all optimized frames).
There was no global deoptimization triggered by the profiled code.
There was one global deoptimization triggered by the profiled code.
There were {{DeoptAlls}} global deoptimization triggered by the profiled code.
There was no On Stack Replacement performed while executing the profiled code (normal if the code lacks long-running loops with many iterations).
There was one On Stack Replacement performed while executing the profiled code.
There were {{OSRs}} On Stack Replacements performed while executing the profiled code.

On Stack Replacement detects routines containing hot loops that are being interpreted, and replaces them with specialized or JIT-compiled code.

No OSR was performed during this profile.
Local deoptimization happens when a guard in specialized or JIT-compiled code fails. Since the code was produced assuming the guard would hold, the VM falls back to running the safe, but slower, interpreted code.

No local deoptimizations occurred during this profile.
Global deoptimization happens when an event occurs that renders all currently type-specialized or JIT-compiled code on the call stack potentially invalid. Mixins - changing the type of an object in place - are a common reason.
