The
io_optimized/SbqSpeedupstorage mode follows the DiskANN approach more closely thanstorage_optimized/SbqCompression, but by storing neighbor vectors inSbqNode, the index size becomes bloated and benchmarks performed poorly. Thus it was never documented externally or used anywhere afaik. This CR simplifies the code by removing this storage mode.
