Some background. I am building a new system that is using some tables from an old system.

so for each user on this new system I need to go to the old system and total up their sales. Currently it takes between 2-5 minutes to load.

public static List<DailyTeamGoal> GetListDailyTeamGoals(int teamId)
{
    string teamGoal = "";
    List<ProPit_User> lstProPit_User = new List<ProPit_User>();
    using (ProsPitEntities db = new ProsPitEntities())
    {
        // Find the team
        Team team = db.Teams.Where(x => x.teamID == teamId).FirstOrDefault();

        if (team != null)
        {
            // Grab team goal
            teamGoal = Convert.ToString(team.goal);
        }
        // Make a list of all users who are on the team
        lstProPit_User = db.ProPit_User.Where(x => x.teamID == teamId).ToList();
    }

    List<DailyTeamGoal> lstDailyTeamGoal = new List<DailyTeamGoal>();
    using (TEntities db = new TEntities())
    {
        //have to get every day of the month
        DateTime dt = DateTime.Now;
        int days = DateTime.DaysInMonth(dt.Year, dt.Month);
        decimal orderTotal = 0m;
        for (int day = 1; day <= days; day++)
        {
            // For every day in the month total the sales
            DailyTeamGoal dtg = new DailyTeamGoal();
            dtg.Date = day.ToString(); //dt.Month + "/" + day; + "/" + dt.Year;
            dtg.TeamGoal = teamGoal;
            decimal orderTotalRep = 0m;
            foreach (var propit_User in lstProPit_User)
            {
                DateTime dtStartDate = Convert.ToDateTime(dt.Month + "/" + day + "/" + dt.Year);
                DateTime dtEndDate = dtStartDate.AddDays(1);
                var lstorderTotalRep = (from o in db.Orders
                                    where o.DateCompleted >= dtStartDate
                                    where o.DateCompleted <= dtEndDate
                                    where (o.Status == 1 || o.Status == 2)
                                    where o.Kiosk != 0
                                    where o.SalesRepID == propit_User.SalesRepID
                                    orderby o.OrderTotal descending
                                    select o.OrderTotal).ToList();
                       
                foreach (var item in lstorderTotalRep)
                {
                    //orderTotalRep =+ item;
                    orderTotalRep += item;
                }
            }

            orderTotal += orderTotalRep;
            dtg.DailyTotal = orderTotal;

            lstDailyTeamGoal.Add(dtg);
        }
    }

    return lstDailyTeamGoal;
}

The above code will use my site to find the teamID the logged in person is on. It will then find all members who are on that team. For each member it finds it will calculate the total sales and then spit me back a list. Any way to speed this up?
