C# 在asp.net中使用datalist控件显示SQL Server数据库的结果会占用时间

我有3个单选按钮业务、联系人、地址

三个数据列表：

业务：显示公司名称、员工姓名、电子邮件ID、联系人、网站地址

联系人：显示员工姓名、联系人

地址：EmaiID，公司名称，网址

在检查单选按钮时，我显示相应的数据列表

对于DataList业务，我有>1000行的记录，当我选中单选按钮时，显示结果需要时间

我应该怎么做才能使我的应用程序平稳快速地运行？我正在使用字母分页来按字母顺序显示数据列表结果。我希望一次显示1000条以上的记录，可能记录数大于或等于5000条

这是我的存储过程：

if(@type = 'Business')
begin
    if(@Utype  ='1' )
    begin
        IF (@Alphabet = 'A' and @name = '' and @company = '' ) 
        BEGIN
           SELECT  
               Company, Address, CardDetail.Name, Email, Mobile, Telephone, Fax, Web, Job, 1, createdby
           FROM 
               CardDetail   
           WHERE 
               Company LIKE 'A%' 
               AND (ViewType = 'C' OR ViewType = 'A' OR createdby = @uid) 
        END

        IF (@Alphabet <> 'A' AND @name = '' AND @company = '') 
        BEGIN
            SELECT  
               Company, Address, Name, Email, Mobile, Telephone, Fax, Web, Job, 2, createdby
            FROM 
               CardDetail  
            WHERE 
               Company LIKE @Alphabet + '%' 
               AND (ViewType = 'C' OR ViewType = 'A' OR createdby = @uid) 
            ORDER BY
               Company ASC
        END

        IF (@name <> '' and @company <> '')
        begin
           SELECT DISTINCT 
              Company, Address, Name, Email, Mobile, Telephone, Fax, Web, Job, 3, createdby 
           FROM 
              CardDetail  
           WHERE 
              Company = @company 
              AND Name = @name  
              AND (ViewType = 'C' OR ViewType = 'A' OR createdby = @uid) 
           ORDER BY 
              Company ASC
end

页面加载

     protected void Page_Load(object sender, EventArgs e)
    {

                Business.Visible = false;
                Address.Visible = false;
                Contact.Visible = false;
                dl_company.Visible = false; 
                ViewState["CurrentAlphabet"] = "A";
                this.GenerateAlphabets();
     }

是不是查询太慢了？还是实际的Web UI？C代码？您应该从分析SQL开始，通过SSMS查看查询需要多长时间。开始时间：2014-10-25 14:04:13.960结束时间：2014-10-25 14:04:13.973总计：13ms
