We've been playing around with a "Proof-of-Concept" (PoC) by Jason Meyer that extends the "Lightning-Fast Alternative" to using "Count ( )" function, first published by Daniel Wood in December of 2010 — deriving related records counts, sums and averages of the fields across those related records in the same way as Daniel's "Get ( FoundCount )" method.
Feedback and results from benchmarking the usefulness and performance of this PoC are encouraged from all. Rather than do a double posting (and, for context), here's the link to a response I posted (with the technique file) in another recent discussion on deriving counts from related records within a portal…
