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 attempts ⓘ The number of times a potential trace is identified. Specifically, this occurs in the JUMP BACKWARD instruction when the counter reaches a threshold.	3,120
Traces created ⓘ The number of traces that were successfully created.	480	15.4%
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.	2,760	88.5%
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 abandoned because it it too short.	2,640	84.6%
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%
