Inaccurate Span Duration Measurements with `Effect.all` and Concurrency

const [activeViewVersion, booksClosedDate, legalEntityPreferences, ledgerName] =
    yield* Effect.all(
      [
        getActiveViewVersion(legalEntityId, viewType),
        getBooksClosedDate(legalEntityId),
        getLegalEntityPreferences(legalEntityId),
        getLedgerType(legalEntityId),
      ],
      { concurrency: "unbounded" }
    ).pipe(Effect.withSpan("Effect.all"))
