是否可以加速从C＃处理此存储过程？

Question

我从C＃调用SQL Server存储过程。只要我将SqlCommand CommandTimeout设置得足够高，它就会起作用 - 返回数据 - 但它比绝对零度的糖蜜慢。

我如何调用可以加快进程的存储过程？我是这样做的：

DataTable dtFillRateResults = SqlDBHelper.ExecuteSQLReturnDataTable(FILL_RATE_BY_DISTRIBUTOR_BY_CUSTOMER_STORED_PROC, CommandType.StoredProcedure,
            new SqlParameter()
            {
                ParameterName = "@Unit",
                SqlDbType = SqlDbType.VarChar,
                Value = _unit
            },
            new SqlParameter()
            {
                ParameterName = "@Member",
                SqlDbType = SqlDbType.VarChar,
                Value = _memberId
            },
            new SqlParameter()
            {
                ParameterName = "@BegDate",
                SqlDbType = SqlDbType.DateTime,
                Value = Convert.ToDateTime(_dateBegin)
            },
            new SqlParameter()
            {
                ParameterName = "@EndDate",
                SqlDbType = SqlDbType.DateTime,
                Value = Convert.ToDateTime(_dateEnd)
            }
);

以上调用SqlDBHelper.ExecuteSQLReturnDataTable()，即：

public static DataTable ExecuteSQLReturnDataTable(string sql, CommandType cmdType, params SqlParameter[] parameters)
{
    using (DataSet ds = new DataSet())
    using (SqlConnection connStr = new SqlConnection(FillRateRptConstsAndUtils.CPSConnStr))
    using (SqlCommand cmd = new SqlCommand(sql, connStr))
    {
        cmd.CommandType = cmdType;
        cmd.CommandTimeout = EXTENDED_TIMEOUT;

        foreach (var item in parameters)
        {
            cmd.Parameters.Add(item);
        }

        try
        {
            cmd.Connection.Open();
            new SqlDataAdapter(cmd).Fill(ds);
        }
        catch (SqlException sqlex)
        {
            for (int i = 0; i < sqlex.Errors.Count; i++)
            {
                var sqlexDetail = String.Format("From ExecuteSQLReturnDataTable(), SQL Exception #{0}{1}Source: {2}{1}Number: {3}{1}State: {4}{1}Class: {5}{1}Server: {6}{1}Message: {7}{1}Procedure: {8}{1}LineNumber: {9}",
                    i + 1, // Some users would get the fantods if they saw #0
                    Environment.NewLine,
                    sqlex.Errors[i].Source,
                    sqlex.Errors[i].Number,
                    sqlex.Errors[i].State,
                    sqlex.Errors[i].Class,
                    sqlex.Errors[i].Server,
                    sqlex.Errors[i].Message,
                    sqlex.Errors[i].Procedure,
                    sqlex.Errors[i].LineNumber);
                MessageBox.Show(sqlexDetail);
            }
        }
        catch (Exception ex)
        {
            String exDetail = String.Format(FillRateRptConstsAndUtils.ExceptionFormatString, ex.Message, Environment.NewLine, ex.Source, ex.StackTrace);
            MessageBox.Show(exDetail);
        }

        return ds.Tables[0];
    }
}
