Research direction

Start by reproducing the reported QueryAsync full-table query with 20,000 rows and 52 columns, comparing the 0.5-second database time with total time. Measure the reflection or object-mapping portion separately; done means identifying the source of the delay and documenting a concrete optimization or limitation.
