SQL Server Standard Edition hobbles batch mode pretty badly. DOP is limited to two, and there’s no SIMD support. It’s totally possible to have batch mode queries running slower than row mode queries, because the row mode queries can use much higher DOPs and spread the row workload out.
I’d almost rather use indexed views in Standard Edition for large aggregations, because there are no Edition-locked enhancements. You’ll probably wanna use the NOEXPAND hint either way.
