      SPM-3754 added workloads comparing the performance of sort merge in SBE and classic https://github.com/10gen/dsi/tree/master/workloads/query-execution/sort-merge. The analysis in https://docs.google.com/document/d/1C-h-jRNpgCXSIBPPBod4Re6uPYX1E0Jav93TP0AX9Uw/edit?usp=sharing reveals that SBE performance is worse for these especially when there are many unique values in the data. We should investigate why this is the case and look for opportunities to improve performance.
