Garbage Collection Pause Probability Calculator

Estimate JVM/CLR garbage collection pause frequency and duration based on heap size, allocation rate, and GC algorithm. Stop-the-world pauses = heap_size / (alloc_rate × GC_efficiency).

How It Works

Estimate JVM/CLR garbage collection pause frequency and duration based on heap size, allocation rate, and GC algorithm. Stop-the-world pauses = heap_size / (alloc_rate × GC_efficiency)

Each component has a specific meaning:

  • Heap size — The heap size recorded for the scenario being assessed.
  • Allocation rate — The allocation rate recorded for the scenario being assessed.
  • GC algorithm — The gc algorithm recorded for the scenario being assessed.

Note: Interpret the gc pause probability result against the thresholds and context described above.

How to Use

Enter the heap size, allocation rate, GC algorithm for the scenario you are assessing. Estimate JVM/CLR garbage collection pause frequency and duration based on heap size, allocation rate, and GC algorithm. Stop-the-world pauses = heap_size / (alloc_rate × GC_efficiency). Use the gc pause probability result to inform your calculation.
