# Columnar CP tool backend performance tests

* During (ongoing) refactor added integrated benchmark to [measure](https://docs.google.com/spreadsheets/d/1psLklZk6B7xcOz2Zijb0vB8AvIuObxHz6v-mLHfUqrw/edit?usp=sharing) .bold[time spent in tool] (not i/o) and compare to xAOD model

* During (ongoing) refactor added preliminary integrated benchmark to [measure](https://docs.google.com/spreadsheets/d/1psLklZk6B7xcOz2Zijb0vB8AvIuObxHz6v-mLHfUqrw/edit?usp=sharing) .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
* Show .bold[substantial speedups] for migrated tools: .bold[columnar is 2-4x faster] than xAOD interface
- Time for i/o and connecting columns not included in the performance comparisons (not optimized in the tests, so removed from benchmark)
