i see that my site is a little slow in my localhost it is fast but in the server not but i see that videos are displayed without problems so i dont think that is from bandwith but i am not sure which are the main things that make a page go slow? sessions can be one of that?? or connections with database??or something else?
View 8 Repliesi have developed an ERP in asp.net 3.5. The problem is that when published and as well as during development, the execution speed of page is very slow. I have off the compilation mode in web.config and also get all the data in page load and then filter it using Dataview rowfilter property but i can't get much better speed.
View 5 RepliesOver the last week I've been investigating an issue for one of our clients whereby the initial page load following a deployment of their website takes around 1 minute, resulting in unacceptable downtime for end users. This was happening not only for code deplyments (bin dll's and .config files) but also if there were large numbers of .aspx pages updated. For code deployments it's not an issue, but for aspx updates it is; in this particular scenario, we are making use of a 3rd party content management system (RedDot from OpenText) in which every page of the site is published out as a distinct .aspx page. This means that for this website there's somewhere in the region of 2,400 separate .aspx pages. I realise this isn't an ideal situation but we're working within the constraints of the CMS, and we managed to correlate the instances where the site was unresponsive with App pool restarts, which also corresponded to publications of of .aspx pages.
I found an article by Tess Ferandez [URL] which describes all the reasons why the app pool may restart, and it does seem that if more than 15 .aspx pages are changed then the app pool will recycle and the pages will be re-compiled. Another msdn article [URL] then gave me a few pointers on how to start addressing this problem, and for the moment I've set a flag on the compilation options to prevent batch compilation:
<compilation batch="false">
This means that the initial page load now takes around 6 seconds instead of 1 minute, which is a great improvement. However, I also used the "Compilations Total" performance counter to investigate the number of pages that have been compiled by ASP.NET for my site and was quite surprised that the total number of pages that get compiled peaks at 44, which is odd given that there are 2,400 aspx pages in the site. If the batch flag is set to false, the counter slowly increments by 1 page at a time as you click around on the site; if batch mode is true, the initial compilation takes the number straight to 44 over the course of ~60 seconds. What I'm really struggling to understand is why all 2,400 pages aren't compiled. Does anyone have any inside info on what might be going on as all the documentation I've read seems to indicate that all of the pages should be compiled and this counter should be much higher.
When I browse the asp.net pages on local host, only IE renders pages very fast. In every other browser I have a delay of 1 second or so. Why is that happening and is there any way to speed up the response time in other browsers (web.config, IIS setting)?
View 2 RepliesDo you know of a library/httpmodule for logging slow loading pages (perhaps for a specific treshold) in an ASP.NET environment?
Google did not yield any results.
It would not be too hard to implement on my own, but why re-invent the weel.
I'm doing a web request that is too slow. It takes around 3.2 seconds to GetResponseStream() and .8 seconds to ReadToEnd() If I run the same request in a web browser I get a response in less than a second... I'm wondering what I can do to speed up the request and what might cause it to be slow? Based on other questions I saw here, I disabled the proxy in app.config + enabled max connections, just in case (it's still slow). The section I added was:
<system.net>
<defaultProxy enabled="false">
<proxy/>
<bypasslist/>
<module/>
</defaultProxy>
<connectionManagement>
<add address="*" maxconnection="65000" />
</connectionManagement>
Here's a screenshot of what the code looks like and what is slow:

View 3 RepliesAll of a sudden my debugging is taking forever to start on localhost (several minutes). It also takes a long time to return to the vwd after I stop debugging.
I haven't done anything that I can think of that would change anything (it has worked in the past, although the slow stop may have been there for some time.
The only thing I did was to add another user to the membership db.
I think it's a problem with starting the localhost development server.
Having real trouble using my local host to test sites. It runs extremely slow! Sometimes up to a minute to load a page. I'm using firefox and the sites i'm testing run fine on other developers in my office local machines/ on the production server.
I've gone through the normal things :-
Disabled IPv6
Not running in debug mood Put the site in the highest app pool (High Isolated) on IIS 6.Taking of firewalls etc.The problem only seems to occur when hitting pages which contain some form of .net code in the code-behind.
Appreciate that this a little bit of a vague topic / stab in the dark but would appreciate any sort of advice - it's horrible waiting a minute each refresh to try out a change!
I have a page that has 5 sections. Each section takes about 1 second to render.
Page_Load()
{
RenderSection1(); //1 sec
RenderSection2(); //1 sec
RenderSection3(); //1 sec
RenderSection4(); //1 sec
RenderSection5(); //1 sec
}
I would like to speed up the loading of this page. But at the same time make sure that it don't slow down performance of other parts of web application and also do not crash the IIS.
The are several approaches:
Use AJAX requests. Needs to be MVC style requests to Controller or Web Service. Using UpdatePanel around each section will not work - since if I try to submit refreshes to multiple UpdatePanels at the same time using approach here: [URL], the last request will always win: [URL] Use ASP.NET threads described in answer to right way to create thread in ASP.NET web application. So I would use a separate thread for each call: RenderSection1, RenderSection2, etc... Move the logic that takes up time, usually DB requests, into Application Service class in another DLL or External Web Service. Something like
OrderDTO GetDataForViewOrder(int orderID)
{
}
and use multiple threads in that DLL. This approach seems to provide the best scalability, but also introduces UI details into Application Services layer.
I've been using things like Firebug and YSlow, so I'm not really looking for advice on increasing page load speeds, but I'm wondering does extra imports or using, especially if your importing or using classes that aren't necessary, cause a page to load slower?

View 2 RepliesWe have a windows service running that listens on e.g. port 9999. Now we want to be able to send a TCP packet through an ASPX page to that service. Both the service and ASP.NET WebApp run on the same server.
The problem is that this works fine on my dev machine (without IIS though, through Visual Studio Web Server) and on our older Win 2003 Server machine. But it doesn't work on our new Win2008 R2 Server. The packet just won't arrive.
I'm absolutely clueless as to what the problem may be. I'm the only one wanting to send TCP packets through an aspx site.
What I have tried so far:
1) Changing the identity of the corresponding Application Pool
2) Disabled the Firewall
3) In web.config set the trust level to "Full" (which seems to be default anyways)

i hit a case when my page loading is very very slow. I have find out that my page is slow for no reason. The read data process from database is fast and all the server code execute quite fast. The problem is the page loading process is slow, very slow. I am thinking one of the possible cause is jquery itself.
View 3 RepliesI'm writing a simple web site using codebehind for each page, however using the "codefile" directive, not "codebehind" as such, because I'm not precompiling. I'm just using a text editor to edit the aspx and codebehind files. Problem is, every time I make a change to the code or the aspx file, and refresh the page in the browser, it takes a 2 or 3 seconds to come up the first time, like it's doing an on-demand initial compile. I assume that's what it's doing, as after the initial load, the page refreshes without any delay at all.
This behaviour is quite frustrating when making small changes to the html or code. I'm coming from classic ASP, where you could edit-refresh-edit-refresh etc. all day without your "stride" being broken by waiting for a "compile", you know? So I'd love to know if there's a setting which prevents this initial delay. When I want to deploy, I can do a compile or something, but while making lots of small edits, I just need the page to run without that initial delay.
I'm more into the LAMP stack, but I've been asked to work on a site that is running Windows and IIS 2008. I'm a beginner with IIS, so please be patient with me on this, and please ask me to provide more information if that is needed to determine. I read the answer here (Slow first page load on asp.net site), but it seems like if I go to the site with one browser it takes long to load the first page, then fast on all other pages, then if I open up another browser, it's the same thing, so it's not something that is saved on the server, but per session? Is there a way to have the application running at all times? Right now it is taking 12 to 15 seconds for the first page to load. I have access to the WebControlCenter and FTP.
View 3 RepliesI have an application that runs perfectly fine and fast in IE 7. There are certain pages in the application that use the AlwaysVisibleExtender control.
However, when I run the app in IE 8, the same exact pages seem to lock up for roughly 5 seconds before they render completely. What's weird is that the page shows all the contents except for the alwaysvisibleextender and relating panel. Then after the 5 seconds the panel shows. During that 5 seconds the page cannot be navigated or scrolled. This is not really acceptable.
I've developed a web page Client.aspx that is used for editing a client. This application has been deployed and I made sure that debug='false'.Upon selecting a client from the dropdownlist, his/her information is retrieved for editing. This retrieving process is very slow( about 9 seconds).Except this DropDownList, all the other controls on this page are within the Update Panel. There are 2-3 other Update Panels within the main Update Panel.
When a client is selected from the DropDownList, the Client_ID (DataValueField) is used to retrive the informationSELECT * FROM CLIENTS WHERE Client_ID=1576
This method returns a dataset.In the calling method I'm assigning these values to the respective fields.Some JavaScript is used for validating Phone#.I also have a RadioButtonList on this page.

in the last period i am working to do my site faster i think it has been faster in many parts
the last part that i think that has problem is the page of the forum that posts are displayed
the strange is that although the first time the page is loaded fast,then when i select to display different data(i click a button that shows the data that i want to be displayed) the page is very slow
these buttons are created dynamicaly with controls.add(button) i dont know if it has to do with delay
gep another time had suggested to use trace but i didnt found how to use trace
i add trace=true in the page but nothing happens where can i see trace results??
Every now and then (always after a long period of idle-time, e.g. overnight) when I access a site built using asp.net - it takes around 15 seconds to load the page (15 seconds before I see any progress whatsoever, then the page comes up fast).Further pages on that site, or refreshes, are quick as usual - they are also fast on other machines, only the first one seems to take the 'hit'.
Page tracing never through anything up (whole cycle was a fraction of a second) So my question is where else should I be looking? Perhaps IIS? Or could it still be my asp.net app and I'm just looking in the wrong place (the trace) for clues?As I don't have much control over the IIS server, anything I can check through asp.net would be more helpful, before I go ask that particular admin.
