Execution counts

Execution counts for Tier 1 instructions.

The "miss ratio" column shows the percentage of times the instruction executed that it deoptimized. When this happens, the base unspecialized instruction is not counted.

Allocations, frees and dict materializatons

Below, "allocations" means "allocations that are not from a freelist". Total allocations = "Allocations from freelist" + "Allocations".

"Inline values" is the number of values arrays inlined into objects.

The cache hit/miss numbers are for the MRO cache, split into dunder and other names.

Optimization (Tier 2) stats

statistics about the Tier 2 optimizer

	Count	Ratio
Optimization attempts ⓘ The number of times a potential trace is identified. Specifically, this occurs in the JUMP BACKWARD instruction when the counter reaches a threshold.	1,680
Traces created ⓘ The number of traces that were successfully created.	340	20.2%
Trace stack overflow ⓘ A trace is truncated because it would require more than 5 stack frames.	0	0.0%
Trace stack underflow ⓘ A potential trace is abandoned because it pops more frames than it pushes.	780	46.4%
Trace too long ⓘ A trace is truncated because it is longer than the instruction buffer.	0	0.0%
Trace too short ⓘ A potential trace is abandoced because it it too short.	1,340	79.8%
Inner loop found ⓘ A trace is truncated because it has an inner loop	0	0.0%
Recursive call ⓘ A trace is truncated because it has a recursive call.	0	0.0%
Low confidence ⓘ A trace is abandoned because the likelihood of the jump to top being taken is too low.	80	4.8%
Executors invalidated ⓘ The number of executors that were invalidated due to watched dictionary changes.	0	0.0%
Traces executed ⓘ The number of traces that were executed	8,092,443

	Count	Ratio
Optimizer attempts ⓘ The number of times the trace optimizer (_Py_uop_analyze_and_optimize) was run.	340
Optimizer successes ⓘ The number of traces that were successfully optimized.	340	100.0%
Optimizer no memory ⓘ The number of optimizations that failed due to no memory.	0	0.0%
