Table 4. Performance of TORO and XGandalf on various hardware accelerators on lysozyme over 953 indexable frames containing 80 strong reflections identified using peakfinder8.

The CrystFEL configuration indicates that the performance test was done using indexamajig with flags --no-revalidate --no-retry --no-refine --no-check-peaks --no-multi and the --profile flag, while Python refers to standalone Python code. Time is reported in milliseconds.
