The first pass of two-pass rotation indexing was the slow "getting there" phase. Profiling RunIndexing showed the cost is the serial Ceres candidate refinement (up to 4 FFT candidate cells x 2 XtalOptimizer solves each), not spot finding or the cuFFT kernel. - XtalOptimizer: add a num_threads arg (default 1) so a caller running a few refinements concurrently can give each several cores. - RotationIndexer::RunIndexing: seed the candidates serially, run their up-to-8 XtalOptimizer solves concurrently (4 Ceres threads each), select serially in candidate order (identical result). ~10-13x on the candidate loop. - Rugnux: feed both first-pass schemes (spread + wedge) serially, then run their RunIndexing() passes in parallel - overlapping one scheme's cuFFT with the other's Ceres. Size the FFT indexer pool to 2 for the rotation path (it fires only twice) instead of the default 4, avoiding wasted cuFFT-plan init. First-pass wall 2.1-6.5x faster across a 12-crystal battery; whole lysoC run 17.7->10.5s. All 12 crystals bit-identical (scheme, validation count, space group).
