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.

Call stats

Inlined calls and frame stats

This shows what fraction of calls to Python functions are inlined (i.e. not having a call at the C level) and for those that are not, where the call comes from. The various categories overlap.

Also includes the count of frame objects created.

	Count	Ratio
Calls to PyEval_EvalDefault	24,001,320	5.4%
Calls to Python functions inlined	418,551,000	94.6%

Object stats

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.

	Count	Ratio
Allocations from freelist	36,034,100	42.9%
Frees to freelist	36,034,040
Allocations	47,991,220	57.1%
Allocations to 512 bytes	47,991,220	57.1%

GC stats

GC collections and effectiveness

Collected/visits gives some measure of efficiency.
