Improving The Web Site Performance?
Jun 29, 2010
I have a pretty big web site (asp.net web) and I have used JavaScript intensively (jquery,custom javascipt, etc) and also The theme and CSS. Right now I have a huge amount of js and css files in my system and I am thinking about minifying and smashing the js and css to improve the performance. So, please advice me the suitable tools and technologies to be used and please suggest me the best practices to be applied in these scenario.

In my webpage, the page uses lots of images and css. The time taken to load the initial home page is huge.What are the ways,which can be done in IIS 6.0 to improve the performance?I checked few results in google, which talked about File expiration policy and enabling http compression in IIS 6.0. In the Enable content expiration, what value should be ideally used?In the Custom Http header, what should be added to improve the performance.

I have developed a gridview which has 7,000 records with some filtering. However, theuser is compaining that it is too slow. It seems to me that if the records were stored in memory it would be much faster. This is caching, I think. Is that the case? Can you updaterecords this way? Can you cache with an Access database or do you have to use SQL Server? Can you think of any other ways to improve

I have a site running on.NET 4 and it seems sluggish compared to its .NET 3 counterpart even though it is running on a faster box. Is there some type of guide for recommended optimizations on the server to increase performance?

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.

I am having trouble with the performance of a web site... Some SQL queries are killing the server. But, as the title of this post mention, I looked at the OutputCache page directive to improve performance of the site. Although, I came across some questions regarding this directive:
1- If I have a web-user control that declares an OuputCache directive in a page that has one too, which one will "win"?
2- What's the best pratice regarding the duration ? I'd love to have a sliding window too.

I want to build a high traffic video site, which has many videos and visitors, using ASP.NET. But I have no experience of high traffic sites and video sites. Anyone can give me some stuff to read or some keywords for me to google? In the performance point of view.PDATE: I said our site is similar to Youtube, but that just meant that the site structure would be similar to Youtube. We won't have that high traffic.

I need to include an offsite javascript file on my page, however I don't want it to be able to affect the performance of my site, in case the server where the javascript is on is down or not responding.
What I'd like to know, is if it's posible with javascript to make some sort of wrapper function to ensure that the page where the offsite javascript is hosted is responding within an acceptable timeframe.
I've considered adding the "defer" attribute to where I include the javascript, but that would as far as I know still leave the site hanging after the rest of the page is loaded.
If it's not possible to do in javascript are there any good alternatives?
My site is made C# asp.net.

I'm doing a timesheet program. In this timesheet program, I have a default button. If a person doing a same task everyday, they can just fill out the task description & click on default button, it will add that task for 5 days.my question is that my button click has to hit database 7 times. Is there anyway that I can improve this?

This is a continuation on this question:The problem is simple. I need to call methods from a REST web service which controls several tables. One table is a snapshot table which contains records with huge XML files. Each XML file is basically a backup from another database. This backup XML is then sent to customers who use the data as read-only information in another product. Basically, the data in the XML are lists of companies, products, business rules and whatever more. And no, those customers work offline most of the time, so they cannot get the data live.Walking through the list of snapshots is tricky: XMLData.Snapshots.Skip(N).Take(1).First(); but it works very nice. It's the answer of the previous Q.But there are three other lists of data that I need to walk through. These are called Changes, Errors and Messages. They contain (1) changes to the data, (2) errors that occurred during modifying the data and (3) generic messages. All of these records are linked to a snapshot record. Thus a single snapshot can contain multiple changes, errors and messages.
I still cannot access the server code but since there's a REST service wrapped around an entity framework exposing most of the functionality, I can still use that service. (And that service is only accessible internally, on the Intranet. This is basically what I have to work with. And while the lists of changes, errors and messages are relatively small, the snapshots are still huge.
The problem is that I now want to generate a client-side report of the changes, errors and messages, but without grouping them by snapshot! They need to be grouped by date. But each record also needs to show the title of the snapshot, which causes me some incredible headaches...When walking through e.g. the Changes with the regular foreach instruction I can load the Snapshot data by using XMLData.LoadProperty(Change, "Snapshots"); but since the snapshot record itself is generally about 300 MB, this just slows the whole thing down to a crawl. (There are tens of thousands of these records in total!) So I need a faster solution, without having to modify the server code.
Yeah, okay. Modifying the server would be the proper way but that's not possible. It's in production and this list isn't important enough to require an upgrade of the server. Basically, I'm not allowed to modify any server-code for now. (But they still want this list.)The application I'm working on is something that just needs to run once per week or per month. But with the current amount of records, I estimate it would take more than two days to finish. The data itself will be updated a few times every office day and snapshots are created every week or so on the server. Errors can always be generated when users start browsing the site which maintains the data but in general, there will be about 50 changes and 4 errors per week, plus a few messages when the server goes down and up again or when snapshots are generated.

I have developed a website in asp.net framework 2 . This website is being hosted in two different servers without any change in code. My issue is about the performance of these 2 sites. One website is taking much time for inserting datas to the DB (SQL server 2005). 2 websites are having different DB server.
I think the issue is for the DB server. How can we rectify the DB performance while insertion and Is there any other cause for this permance issue?

I am not sure if this is the right forum. I can not find a forum for LINQ.
I am working on an application using LINQ. Application performance is not up to par and my tests show that it is LINQ queries that are slow. I was wondering if anybody can recommend where I can find an article about optimizing LINQ performance maybe by compilation or other methods.

I have a requirement where I have to transfer a user from Web Site 1 on Server A to web Site 2 on Server B.
On Web Site 1, I have to provide controls to enter user id and password and which have to be validated on Web Site 2 on server B, after validating them I have to redirect the user to Web site 2.
what is best way fo doing it. code examples are greatly appreciated.
Note: On Web Site 2, user login functionality is already existing and it is provided by ASP.Net login control, am not sure how to handle the user login process from two different places.
or is it the best way to move Web Site 2 from Server B to Server A so that, the same login controls will be shown using Iframe on Web Site A.

Using Visual Web Developer 2010 Express. I was used to creating a web app anytime and I would get a default page for starters and be happy. But today I find that when I pick either the ASP.NET Web Site or ASP.NET Web Application templates I get site.master and a bunch of site admin files that I don't want. Alternately when I select the empty versions of those templates, I get almost nothing at all. An almost empty web.config page and no Default.aspx page. There is nothing magical about having a default.aspx page in place, but it is an indicator of a change when I can only get a virtually completely empty website or a website with a bunch of bells and whistles I don't want.
Also, for some reason, when I create a new app or website as just noted, in the Solution Explorer I get aspx.designer.cs files showing as well as web.config files for both debug and release. Somehow some settings and templates must have changed, or am I missing something here? How can I get my settings/templates to go back to the way they were?

I am having a little difficulty trying to wrap my head around site structures. I have quite a large asp.net site, for which: Admins can see a user list, Each user can have many accounts, and for each account can have many items. I can picture this as a breadcrumb trail of editing a particular item. User List > Mr Bob > Accounts > BOB77 > Items > Item32 > Edit
User List = All the users Mr Bob = A user the administrator has selected from the User List Accounts = A list of the user's accounts 12BOB = The administrator has selected the account named 12BOB Items = A list of the items an account contains Item32 = The item that the administrator selected Edit = The action that the administrator wants to do. I can picture how this would look like if it was using ASP.NET MVC with the URL, but I am unsure how to map this out using Webforms, and in the physical filesystem.
This is what I have thought up about how I am guessing the physical structure would look like. Will this have to use session variables to achieve what I am trying to do?
/Users/User/Edit.aspx <- for editing a user
/Users/User/View.aspx <- for viewing a user
/Users/User/Accounts/Default.aspx <- for viewing all accounts
/Users/User/Accounts/Account/View.aspx <- for viewing an account
/Users/User/Accounts/Account/Edit.aspx <- for editing an account
/Users/User/Accounts/Account/Items/Default.aspx <- for viewing all items in an account
/Users/User/Accounts/Account/Items/Item/Edit.aspx <- for editing an item
Where can I read more about this kind of setup in a web application? Or, can someone point me in the direction of an available project that has this kind of layout?

i have an asp.net website which contains a link to a legacy site written in classic asp which has vb 6 classes (dll) in the back ground also.here is what i am trying to achieve:-i want to browse to the asp.net website using IE7,then when the link is clicked then enters the classic asp site i want to start debugging the classic asp and step through it.(also to make things worse, once a the vb6 class is instanciated, and a call make to its method i want to debug the method in the vb 6 code)My system :- XP Pro, IIS 5, Visual Studio 2005 (asp.net project ), Visual interdev 6 (classic asp project) Visual Basic 6 (vb 6 classes compiled into dll)i have been trying everything with no joy, there is lots on the net but nothing seems to have worked.i have the back office components installed so asp debugging is possible, i have configured the asp website s debugging is turned on.if i add a breakpoint to the classic asp site and hit the start button in visual interdev i can step through it fine.My problem is that if i attach interdev to a process (iexplorer.exe or dll.host) then the breakpoints are not hit. if anyone can help me with this it would be great.ont top of that, if anyone can explain to me how to also debug the vb6 dll code in visual basic 6 when it is called from the classic asp site that would be great!

I have 2 sites, one the main product site the other a secure site featuring the basket and checkout processes.
When a user clicks "add item to basket" I am creating a basket in a database and then adding the items to the basket. The theory was then to store the id from the database for the basket (the basketid) in a cookie, redirect the user to secure site, use the basket id from the cookie and display the contents in the basket.
However I am having trouble getting the secure site to use the same cookie. When I redirect the users to the secure site, the basket appears empty. I need to go back to the main site and then back to secure before the cookie appears.
Here is the code for the cookie
[Code]....
And then on the secure site this is how it gets the basket ID from the cookie
[Code]....
But like I say it's having problems. I've tried replacing the cookies with session variables as well but it didn't work.
