Based on an instrumented set of our container classes, it was found that an excessive number of Vector reallocations were occurring in the corner normals code path. The allocations were reduced by increasing inline buffer sizes for the Vectors in question. The total number of reallocs falls from 433k to 194k when importing the Zero-Day FBX scene[1]. Profiling time spent in `MEM_lockfree_mallocN_aligned` falls from ~1.3% to ~1.15% [1] Zero-Day, Open Research Content Archive (ORCA): https://developer.nvidia.com/orca/beeple-zero-day Pull Request: https://projects.blender.org/blender/blender/pulls/117431
