# gzip - evaluation
|
||||
|
||||
Artifacts saved in `evaluation_artifacts`.
|
||||
|
||||
## Performance
|
||||
|
||||
Using the command line
|
||||
|
||||
```bash
|
||||
for i in $(seq 1 100); do
|
||||
perf report 2>&1 >/dev/null | tail -n 1 \
|
||||
| python ../hackbench/to_report_fmt.py \
|
||||
| sed 's/^.* & .* & \([0-9]*\) & .*$/\1/g'
|
||||
done
|
||||
```
|
||||
|
||||
we save a sequence of 100 performance readings to some file.
|
||||
|
||||
Samples:
|
||||
* `eh_elf`: 331134 unw/exec
|
||||
* `vanilla`: 331144 unw/exec
|
||||
|
||||
Average time/unw:
|
||||
* `eh_elf`: 83 ns
|
||||
* `vanilla`: 1304 ns
|
||||
|
||||
Standard deviation:
|
||||
* `eh_elf`: 2 ns
|
||||
* `vanilla`: 24 ns
|
||||
|
||||
Average ratio: 15.7
|
||||
Ratio uncertainty: 0.8
|
||||
|
||||
## Distibution of `unw_step` issues
|
||||
|
||||
### `eh_elf` case
|
||||
|
||||
* success: 331134 (99.9%)
|
||||
* fallback to DWARF: 2 (0.0%)
|
||||
* fallback to libunwind heuristics: 8 (0.0%)
|
||||
* fail to unwind: 379 (0.1%)
|
||||
* total: 331523
|
||||
|
||||
### `vanilla` case
|
||||
|
||||
* success: 331136 (99.9%)
|
||||
* fallback to libunwind heuristics: 8 (0.0%)
|
||||
* fail to unwind: 379 (0.1%)
|
||||
* total: 331523
