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.

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.

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. |
0 | |
Traces created
ⓘThe number of traces that were successfully created. |
0 | |
Trace stack overflow
ⓘA trace is truncated because it would require more than 5 stack frames. |
0 | |
Trace stack underflow
ⓘA potential trace is abandoned because it pops more frames than it pushes. |
0 | |
Trace too long
ⓘA trace is truncated because it is longer than the instruction buffer. |
0 | |
Trace too short
ⓘA potential trace is abandoned because it it too short. |
0 | |
Inner loop found
ⓘA trace is truncated because it has an inner loop |
0 | |
Recursive call
ⓘA trace is truncated because it has a recursive call. |
0 | |
Low confidence
ⓘA trace is abandoned because the likelihood of the jump to top being taken is too low. |
0 | |
Executors invalidated
ⓘThe number of executors that were invalidated due to watched dictionary changes. |
0 | |
Traces executed
ⓘThe number of traces that were executed |
7,681,920 | |

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