Gridview.datasource = dataset();

.NET 4 Performance Issue String IndexOf



I have a performance issue with the new dot net 4.0 framework.

When i use the function String.IndexOf(string, stringcomparison.ordinalignorecase) my execution time is much higher than framework 3.5 (i had 30ms in a loop for 3.5 and 210ms in framework 4)

All other StringComparison mode are really good in framework 4.

Is there an explanation?

performance issue


i am having an issue in queying a table. This is something thats happening since the last 2 days. whenever i try to open a table (rightclick --> open table ) it errors  out saying the query time out period elapsed before the completion of the operation or server is not responding. But when i query select * from tablename..it is taking some time but is returning the results. The query time out period is set to 0(indefinite time out). we have never seen this kind of issue before. There are no open transactions either to assume that something is locking the system(dbcc opentran returns there are no open trans). Wondering why this is happening and also the performance of the system has gone down completely. Please help us in this issue. I checked the indexes for fragmentation and could see in some of them avg_fragementaton_percent like 60, 70, 80. i guess it is not good to have high such a value, so i ran dbcc reindex but still did not improve the performance. the avg_fragmentation was still the same.

Please advice. 

Issue with WCF performance


We have several WCF (3.5 hosted in IIS7) web services that are having some strange and inconsistent performance issues. In some environments they run fairly quickly. In others they time-out even if we significantly increase the timeout. We have tried all of the advice for performance tuning an IIS 7 hosted WCF service to no avail.

The svc log however shows some odd beheavior I am not sure how to interpret. I will get a message saying Opened System.ServiceModel.InstanceContext/..... The next message will say "A message was read". all good except it takes over six minutes sometimes. I do not follow these logs well enough to understand what could be causing this.

If anybody could provide any help or guidance, it would be greatly appreciated.

Best regards,


 Additional information: Just realized that the servers where we are having the large delays reading the message have Symantec "Data Endpoint Security" installed. Seems like it could be related. anybody have familiarity with this AV client and WCF?

Performance Issue.



I have a query which involves a table and a function. Table has got around 59 crores of records and the function returns 56k records. There is a inner join between with function being on the left side. This query takes around 2 minutes to execute. I wanna improve the performance to few seconds.

I made sure that the table has all required indexes but still was not able to improve the performance.

Please suggest what else i can do to improve performance.

Performance Issue


we did a performance check on production and found that an object is missing from the Layout page which causes the below error frequently.

 When we check the log file we get the below error

1. SearchUpgradeGetKeywordPropertyBag keywordsPropertyBag is null

2. Cannot open file "Resources.en-US.resx" for reading.
(#3: Cannot open file "Resources.resx" for reading.)


Most of the time SearchUpgrade and Cannot open file error are followed by While Initializing navigation error.

And we receive a deadlock error in the IIS(ISAPI.dll) at the same time when we receive this error.

One Gridview & Multiple CommandText Issue on Paging


Hi All,

I am using a gridview to display data from two separate functions. [VS 2010 on Framework 4]

This works fine without paging. On paging, clicking 'next page' invokes the older data(of function 1) instead of that in the new function (function 2) Cry


' Function 1

cmd.CommandText = "select * from table1,
Dim dTable As DataTable
Dim dataAdapter As SqlDataAdapter
            dTable = New DataTable
            dataAdapter = New SqlDataAdapter(cmd.CommandText, AquisitionString)

'Function 2

cmd.CommandText = "select * from table2,
Dim dTable As DataTable
Dim dataAdapter As SqlDataAdapter
            dTable = New DataTable
            dataAdapter = New SqlDataAdapter(cmd.CommandText, AquisitionString)

'Handling PageIndexChange

   Protected Sub grdAcquisition_PageIndexChanging(ByVal sender As Object, _
       ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles grdAcquisition.PageIndexChanging

display message if gridview has no row issue


(1) i want to show message if no data row is found in the grid. but my code below does not achieve this. basically if gridview shows data then i want my panel (booking form) to be made visible otherwise hidden. the booking form panel is set to visible false. my else statement is not working...

        protected void btnCheckFlightAvailability_Click(object sender, EventArgs e)
            if (Page.IsPostBack)
                this.gvSingleFlightSearch.DataSourceID = "CheckSingleFlightDataSource";

                if (gvSingleFlightSearch.EmptyDataText != null)
                    pnlFlightAvailableMessage.Visible = true;
                    lblAvailableFlights.Text = "Flight Available";
                    gvSingleFlightSearch.Visible = true;


                        pnlFlightAvailableMessage.Visible = false;
                        lblAvailableFlights.Text = "No Flight Available";
                        gvSingleFlightSearch.Visible = false;

(2) one of the field in my grid view is price while a texbox in my booking form is passenger numbers. how can i use the value entered
