I have an ASP.NET 2.0 web form that is taking almost 30 seconds to load. I am trying to figure out what is going on. I have enabled tracing and put in a whole bunch of Trace.Write statements so I can hopefully see what is going on. The results are very strange. They look like this...
aspx.page Begin Load 0.000245093984962406
MyEvent1 0.000446804511278195
MyEvent2 0.000464654135338346
MyEvent3 0.000477984962406015
aspx.page End Load 23.9897560037594
So all of the Trace statements that I put in (MyEvent1, MyEvent2, MyEvent3) fire very quickly. The last Trace statement that I put in is right at the end of the Page_Load event. So can anyone tell me what might be happening right after the final statement in the Page_Load event but before the End Load happens? I can't figure out what could be causing this to take so long. Is there some other way I can troubleshoot what is happening during the Page_Load event?
UPDATE - Adding code
protected void Page_Load(object sender, EventArgs e)
{
Trace.Write("Starting Page Load");
if (!Page.IsPostBack)
{
Trace.Write("Setting Body Tag and Meta Tags");
HtmlGenericControl _mainBodyTag = (HtmlGenericControl)Page.FindControl("mainBodyTag");
_mainBodyTag.Attributes["class"] = "drill membership";
HtmlMeta _meta = new HtmlMeta();
_meta.Name = "publication_date";
_meta.Content = Sitecore.Context.Item.Statistics.Updated.ToShortDateString();
Page.Header.Controls.Add(_meta);
Trace.Write("Binding data");
this.BindData();
}
}
protected void BindData()
{
//Feature
Trace.Write("Setting Featured Item Info");
litFeatureType.Text = "Report";
hypTitle.Text = _feature.Fields["Title"].Value;
hypTitle.NavigateUrl = LinkManager.GetItemUrl(_feature);
hypReadMore.NavigateUrl = LinkManager.GetItemUrl(_feature);
hypFeature.NavigateUrl = LinkManager.GetItemUrl(_feature);
litFeatureText.Text = _feature.Fields["ShortDescription"].Value;
litDate.Text = ((DateField)_feature.Fields["ReleaseDate"]).DateTime.ToShortDateString();
litLocation.Visible = false;
pnlMeeting.Visible = false;
//News
Trace.Write("Getting Member News");
List<Item> _memberNews = _repository.GetMemberNews();
rptNews.DataSource = _memberNews;
rptNews.DataBind();
//Lower Left
Trace.Write("Getting lower left content");
Item _home = Sitecore.Context.Database.SelectSingleItem("/sitecore/Content/Home");
litLowerLeftContent.Text = _home.Fields["Lower Left Content"].Value;
//Lower Right
Trace.Write("Getting lower right content");
litLowerRightContent.Text = _home.Fields["Lower Right Content"].Value;
//Other Member Resources
Trace.Write("Getting member resources items");
Item _memberHome = Sitecore.Context.Database.SelectSingleItem("/sitecore/Content/Home/Member");
rptMenu1.DataSource = _memberHome.Children;
rptMenu1.DataBind();
//Membership Stats
Trace.Write("Getting membership stats");
List<MembershipStat> _stats = _repository.GetMembershipStats();
rptStats.DataSource = _stats;
rptStats.DataBind();
litTotal.Text = _totalCount.ToString();
//Rail Content
litRailContent.Text = _home.Fields["Right Rail Middle Content"].Value;
Trace.Write("Finished");
}
