网页提交数据到数据库，用giridview显示数据，查询的数据源数据库特别大，查询时间较长，最后反馈页面是服务超时，怎么解决？
protected void Button1_Click(object sender, EventArgs e)
{
string connstr = ConfigurationManager.ConnectionStrings["connstr"].ConnectionString;
SqlConnection myConn = new SqlConnection(connstr);
myConn.Open();
{
if (myConn.State == ConnectionState.Open)
{
SqlCommand comm = new SqlCommand();

            comm.Connection = myConn;
            //comm.CommandTimeout = 120;
            comm.CommandType = CommandType.StoredProcedure;
            comm.CommandText = "SearchTitle";
            SqlParameter Title = new SqlParameter("@Title", SqlDbType.Char, 128);
            Title.Value = TextBox1.Text;
            comm.Parameters.Add(Title);

            SqlDataAdapter da = new SqlDataAdapter(comm);
            DataTable dt = new DataTable();
            da.Fill(dt);
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
    }
    myConn.Close();
}
    这是后台代码

    以下是存储程序：
    IF object_id('temp0..TitleSearch')   is   not   null      
    BEGIN 
    delete from temp0.dbo.TitleSearch
    END  

declare @DatabaseNameNum varchar(256)
declare @x int
set @x=1
while(@x<12)
begin
set @DatabaseNameNum = 'QunInfo'+cast(@x as varchar)
set @x=@x+1
print @DatabaseNameNum
--end
--循环查询QunInfo1至QunInfo11数据库

declare @sql2 varchar(max)
declare @i int=0
IF object_id('temp0..temp0_test')   is   not   null      
    BEGIN 
        DROP TABLE temp0..temp0_test
        create table temp0..temp0_test(id int identity(1,1),name nvarchar(1000))
    END  
    --declare @tb table(id int identity(1,1),name nvarchar(1000))
 set @i = 1 
set @sql2=' 
        insert into temp0..temp0_test(name)
        select t.name
        from @DatabaseNameNum.sys.tables t
        where t.name like ''Q%'' 
    '
 set @sql2=REPLACE(@sql2,'@DatabaseNameNum',@DatabaseNameNum)--变量替换
 print @sql2
 exec(@sql2)

--查询以Q开头的所有表

declare @sql1 varchar(max)
declare @tb_name nvarchar(100) 
while @i <= cast((select COUNT(*) from temp0..temp0_test) as int)
begin
    select @tb_name = @DatabaseNameNum +'.dbo.'+ name from temp0..temp0_test where id = @i ;
    --SET IDENTITY_INSERT ON
    --SET IDENTITY_INSERT OFF
    set @sql1='insert into Title([QunNum]
                                       ,[MastQQ]
                                       ,[CreateDate]
                                       ,[Title]
                                       ,[Class]
                                       ,[QunText]  )
      select [QunNum]
            ,[MastQQ]
            ,[CreateDate]
            ,[Title]
            ,[Class]
            ,[QunText]  
    from @tb_name with(index(keywords))where Title like ''%@Title%'' 
               '       
     set @sql1=REPLACE(@sql1,'@tb_name',@tb_name)
     set @sql1=REPLACE(@sql1,'@Title',@Title)
     exec(@sql1)
     print @sql1
     set @i = @i + 1
end

--将检索到的数据插入到新表

end
select * from Title
