# Columnar CP tool backend performance tests

.huge[
* During (ongoing) refactor added preliminary integrated benchmark to measure .bold[time spent in tool per event] (not i/o) and compare to xAOD model
* During (ongoing) refactor added preliminary integrated benchmark to measure .bold[time spent in tool per event] (not I/O) and compare to xAOD model
* While direct comparison not possible, tests are as close as possible
- Only involves `C++` CP tool code (no Python involved)
- Uses same version of CP tool
- xAOD includes event store access
* Show .bold[substantial speedups] for migrated tools: .bold[columnar is 2-4x faster] than xAOD interface (EDM access dependent)
- Time for i/o and connecting columns not included in the performance comparisons (not optimized in the tests, so removed from benchmark)
- Time for I/O and connecting columns not included in the performance comparisons (not optimized in the tests, so removed from benchmark)
