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)?

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 am writing an 3-tier enterprise asp.net web application which needs to be very lightweigt to lower the bandwidth usage. I want to speed up ASP.NET web page loading, I have minified all js and css, used AJAX, used less images in page, used paging for grids but still the overall response page size goes to nearly 1Mb because of viewstate hidden fields.
im developing some backends in ASP.NET 2.0 and i have put all the images in Cache, GZIPED my CSS, JS files and everything to speedup the load of each options.
the performance its good and i have no problems with the clients but i want "MORE" fast loads and im looking for some recomendations.
Is important to mention that those websites are using only in intranets so im thinking to implement my next projects using IFRAME for content that way (i think) the options will be loading faster because they not have to load the entire site.
EDIT:
im not using viewstates i wrote HTML (code behing) generated controls and use as less as possible ASP.NET Rich controls, all my static contents are in Static vars (Header, Menu, Footer) but im just looking for speed up a litter more.
After compile my website i compress all the HTML, CSS, JS and use less of those files as possible.
but i was seeying others Backend that loads faster than my and the difference is the IFrame control that they use (i think), we check code, design, etc and we use the same (they use #INCLUDES for static HTML instead STATIC VARS with the HTML)
Is there a way to measure the time elapsed for a web page to execute?
And if so, is it safe to use that figure to estimate the speed of the web page as the number of users grow and the database grows. Ie: if the page currently takes 1 second to process through x amount of rows in the database, to estimate it would take 2 seconds with 2x rows?
I have a web application running on ASP.NET 3.5 which basically stores, retrieves, and allows users to manipulate data from a SQL Server 2005 database. One of the features allows users to search through the records in the database. When the system was first launched last year, there were no records, so searches were lightning fast. However, over the past year, about 100,000 records have been entered, so most searches now take over 15 seconds to perform. I'd like to speed up searches, but there are problems with both of the conventional approaches I can think of:
Caching - The database does all the heavy lifting in this application - the ASP.NET web application is little more than a UI that passes user input to the correct stored procedure, and displays the returned output. The stored procedures are responsible for interpreting user input, applying the business rules, and transforming the underlying tables and views into a context-sensitive result set which the application just displays as is. Unless if there's a way to apply a stored procedure to a C# object/collection (the cached records), and get another C# object/collection back, effectively bypassing the database, I don't think this will work.Stored procedure optimization - There's some optimization potential here, but even a simple SELECT * FROM TheView statement on the underlying view currently takes 11 seconds according to SSMS, and I expect that the amount of time taken will continue to increase as more records are entered.Are there are techniques out there that I'm not aware of, which could be used to bring searching down to a reasonable amount of time (5 seconds or less per search)?

i meaen i want it run on client side only , before i submit by another button, but the problem is it spent more than 2 second to get value
from textbox1 to textbox2 in this case( because i have 101 button run like these), i know that it need time postback to server. i could not use return()false because if i do like that the value from texbox1 will not add into textbox2, 2 seconds is not reach my golf.

View 9 RepliesI'm using Webservice which will return the data from the database through datatable and I'll convert the datatable into byte array. In front end, I'll reconvert the bytearray to datatable and used ajaxloader to display it in the form.. It is dynamic loading. So, for each click, it is taking 10 seconds to retreive the data regardless of the size of the data. So, I used static datatable and I've loaded all data in that datatable in page load event. But, no reaction. It is taking only same time. Even, there is no data to retreive, the ajax loader is going on loading for 10 seconds. Problem is with Ajax or my webservice??

My web server and database server are currently both in the same room. However, the web server might be changed to a different server in another building about a mile down the street. I want to make sure this doesn't have a negative impact on the connection speed between the database and web server. Is there a way to test the connection speed from both web servers to the database?
View 3 RepliesRecently, I added a massive amount of new languages (as RESX files) to an ASP.NET Web Site project in VS.NET 2010.
The project has approximately 50 ASPX pages and did build rather fast, before I added the languages.
Since the languages were added the compiler takes several minutes (well, at least 1-2) until the browser sees a page.
Now I'm currently investigating, whether I could speed up compilation time inside my development environment. I can think of:
Leaving out the RESX files in VS.NET and copy them from another, external folder, when deploying to the web server, only.
Change the project type from Web Site to Web Application.

I have a website that enable the user to upload pics to server (uploaded pics sizes are 300x400 and approximately 270kb). In my app. I am having another page that lists the pics and I am using there an image control for that purpose. The Image control sizes are 80px width, 60px height. My question is how can I improve the download speed by minimizing the images ? Do I have to create a thumbnail for each picture the user upload?

8 dropdownlist using AccessDataSource to reciece data.
It cause 8 sec when a.aspx was completely loaded as i am running localhost enviroment.
If i remove all the dropdownlist databinding, the speed is acceptable.
I though the connection to database is 8 X 10 = 80 times, so it cause a long time.
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.
