I have a problem with the performance of the web site-application . The major problem is when i hit the site from a long distance remote pc all server side events responces are too slow espesially the gridview (paging) , the point is when i used ajax update panel of asp.net it was more slower .
View 6 Replies have a website with MasterPages, on load master page has many database roundtrips and logics implemented.Now, if move to one page to another, the MasterPage get reloaded and all the above mentioned procedures processed again, which again takes a lot of time and as a result my website's response is very slow.For eaxmple, once the default page is loaded, all the child pages can load within the centent area (in ajax style).
tell me some workaround to optimize the site so that it doesn't this procedures repetitively.
I have a drop down list that hides a panel with a bunch of controls when a certain value is selected, and shows the panel again when some other value is selected. This works fine. However it's slow when running both on my local webserver and on my web host, and takes about 1-2 seconds. What could be the reason for this? The only thing I do is to check which value is selected and hides/shows the panel.
View 9 RepliesWhy the ajax control is working slow when i upload to the server? such as the custom validator is slow response in the server, the modal popup box or loading is slow to response or close up after click the ok button. It work fast in the local server.
View 2 RepliesI'm trying to implement AJAX within an existing application and it seems to be running slow.
I have 3 datallist that all have checkboxs. I have buttons that all users to check all checkbox for a specific datalist. I have an update panel around each datalist. When I check and uncheck it seems to be really slow. I also have 3 textboxes and 4
buttons within my update panel.
When I user uses this site it hides and shows different panels and that seems to be really slow when the users press a button. There is no database stuff happening when the slowness occurs.
I have a download button on my website to download an application of mine. It works fine but I noticed people are clicking it repeatedly. The response time is a little slow after you click the button. Not that bad for me but maybe it's worse for some. In the button click sub I have the code to get the file and bring up the download window and I also have code to increment a table for download count and get the IP address of the person who clicked the button. If I just have the code necessary to do the download the download window comes up a little bit quicker. Here's my button click sub :
Code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
'
Dim FilePath As String = Server.MapPath("~/FolderForDownload/MyApplication.exe")
Dim myfile As New System.IO.FileInfo(FilePath)
If myfile.Exists Then
Response.AddHeader("Content-Disposition", "attachment; filename=" + myfile.Name)
[Code] ...
What I've noticed is that when I had Responcse.End() before my code to get the IP address and increment my table and save the IP Address it would skip performing that code so I moved it below the code. It performs the code but I noticed that after you click the button it takes longer before you see the window pop up that asks if you want to Run or Save.
I tried putting the code to get the IP address and increment my table in a separate sub and then call the sub after Response.End() but it still doesn't perform that code unless I call that sub before Response.End().
I'd like to do everything I'm now doing but get the Do you want to Run or Save window to open sooner. I'm getting a number of people downloading my application from overseas and perhaps when it runs the code to identify the IP address it takes longer. I'm not sure but I see people clicking the download button repeatedly. My table records the exact time to the second when they clicked the download button and to take an example, there are 4 consecutive entries with the same IP address and the times are 3:28 PM for all 4 with the seconds being, 13, 15, 16, and 17.
I put a test download page on my website. When I was running in Visual Studio and using a localhost address I was seeing a big difference in how quickly the window opens after you click the download button if there's download code only versus download code with the other code. When I copied the page to my website and accessed the webpage on the internet there didn't seem to be hardly any difference.
Here's a link to the test page on my website if you want to try it out. You don't have to download anything but you can see how quickly the window opens asking if you want to run or save. There are 2 buttons on the page. One says Download Code Only and the other Download Code and Other Code.

I just tried it out and I saw a big difference in time between the two but earlier I didn't. Sometimes I think the added code runs faster and other times slower.
I have a Listview in ASP.NET 3.5 page. When I press the Edit button it takes about 10 seconds before the screen is refreshed.
I have disabled ViewState and SessionState with no improvement to response time.
I'm looking for suggestions of what to look at to improve the response.
I have created a website with asp.net 3.5 and c# (using linq to sql). its a basically a project managment system. bt its very slow when u look at its loading time. my dashboard takes a whole lot of time to load.when i look at other sites created by my colleagues it loads much faster than my site. they have developed it using ado.net + Stored procedures. that made me believe that linq to sql is slower than ado.net + SP combination.to improve my site perfomance using linq to sql.

View 1 RepliesI recently upgraded to Windows 7 Ultimate on my work computer. Before this debugging a website in Visual Web Developer 2008 was really fast - the page loaded up like a normal website would.
Since I've upgraded to Windows 7 the page loads like normal but gets stuck for about 30 seconds at the end of the load - this is slowing me down as I normally need to use the FireBug tool as soon as the page has loaded.
I have a really weird problem that I've been investigating for at least one week now. I deliver a website hosting both ASP classic and .NET 3.5 content in IIS6 on a Windows 2003 server environment with MySQL db backend. The solution has been installed on several servers (some hosted in WMWare) with no problems. On one specific server, also hosted in WMWare, the user experience great performance issues on the website. The problems are most seen when using database resources and is not limited to either .net or asp classic, but I am still not sure that the problem is only related to database calls.
Following components are involved:
IIS6 .NET FW 3.5 MyODBC 3.51 / 5.1 MySQL 4.x
Code executed on the server using all resources above runs smoothly when the IIS is not involved. The website shows times up to 2 minutes to execute code that takes 2 seconds outside the IIS. The exact same code is executed. Using profiling tools, I've seen that the great loss comes within calls to unmanaged code, for example when System.Data.ODBC namespace to calls into myodbc.dll.
The tricky part is: If at least one console user is logged in to the server, the performace problems are not seen anymore. When the user logs out, the problem appears again.I have tried to reinstall all components above, tried different versions of MyODBC, tried different website authentication methods, tried to run website under administrator privilegies, installed various MS KB's with no success.

View 1 RepliesI have noticed two time-related problems with my website:
[1] Slowness of loading the graphics for each page in the browser;
[2] Receiving a "Runtime Error" page in the browser when I do take action on the site (e.g. navigate to another page) within approx. 30 seconds.
Are these problems related to limitations of my web host?
i wanted to know that how to make the website that performance never goes down even if the load is increased up to some extent rather than the general websites.
i am confusued that is this related to the database server or the coding...
Assume the following html form is on [URL]in which you enter first name and last name and click the button.
<body>
<form id="form1" action="Result1.aspx" method="post" >
<p>
First Name:
<input id="FName" type="text" name="FName" /></p>
<p>
Last Name:
<input id="LName" type="text" name="LName" />
<input id="Submit1" type="submit" name="submit" value="submit" /></p>
</form>
</body>
The form1 posts data and you will see the Result on [URL] which simply shows your data.
<body>
<form id="form1" runat="server">
<div>
Result is:<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
Here is a sample code for the result page: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim SB As New StringBuilder()
Dim NVC As NameValueCollection = Request.Form
Dim nextKey As String
For counter As Integer = 0 To NVC.AllKeys.Length - 1
nextKey = NVC.AllKeys(counter)

When my Application face a long-time process, i.e fetch a query (SELECT a, b, c FROM d)This query needs 10 seconds to be completed in the MSSQL Management Studio, but when the ASP.NET application try to fetch it, it refuse to return any response to any other requests made on that Server.
I am hosting my Application on VPS Server with good specifications, and I am giving this example the (SELECT a, b, c FROM d) just to tell you the issue, it can be any process, maybe processing a movie, or even fetching some data through external API that is experiencing some slow-down,or whatever.
I am working on an Asp.net webiste.The response time(in case of a postback) of the pages in the website is ok on my local machine.But when I uploaded the same website to the internal development server and tried to access the server pages from my local machine,its taking bit long(in case of a postback) as compared to my local machine.I do not understand why the same webiste runs slowly on the dev server..
Following is the configuration of dev server.
Microsoft Windows Server 2003 R2 Enterprise Edition service pack 2

E5450 @ 3.00GHZ
3.23 GHZ,2.00 GB of RAM

I've got this problem.I launched an ASP.NET website with the Umbraco CMS on an ISP.(Its just a very basic informative site. nothing special.)When I go want to visit the website however, the first pageload takes a lot of time, sometimes even up to 20 seconds. Of course this is ridiculous. Afterwards, I am able to navigate the site relatively quick.. So every first pageload is slow, then everything is OK, more or less.Does anybody have any idea what the problem could be? Would it be IIS? ASP.NET?

So,I have this code:

I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
View 5 RepliesI'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.
