I have a function that uses Linq to get data from the database and then I call that function in another function to sum all the individual properties using .Sum on each individual property. I was wondering if there is an efficient way to sum all the properties at once rather than calling .Sum() on each individual property. I think the way I am doing as of right now, is very slow (although untested).

public OminitureStats GetAvgOmnitureData(int? fnsId, int dateRange)
    {
        IQueryable<OminitureStats> query = GetOmnitureDataAsQueryable(fnsId, dateRange);

        int pageViews = query.Sum(q => q.PageViews);
        int monthlyUniqueVisitors = query.Sum(q => q.MonthlyUniqueVisitors);
        int visits = query.Sum(q => q.Visits);
        double pagesPerVisit = (double)query.Sum(q => q.PagesPerVisit);
        double bounceRate = (double)query.Sum(q => q.BounceRate);

        return new OminitureStats(pageViews, monthlyUniqueVisitors, visits, bounceRate, pagesPerVisit);
    }
