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.

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. |
3,060 | |
Traces created
ⓘThe number of traces that were successfully created. |
100 | 3.3% |
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. |
280 | 9.2% |
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. |
2,960 | 96.7% |
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. |
0 | 0.0% |
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 |
