Deploy Web Application

Is there any way i can deploy asp web application on multiple systems or multiple iis enabled windows xp systems.

since the application is running very slow when used by around 80 + people...

Re: Deploy Web Application

You might be able to do something with Microsoft's free load distributor, I forget the name but what you can do is you place several web servers in a pool and the software sends the requests in a round robin format.

Its MS Application Request Routing: http://www.iis.net/download/ApplicationRequestRouting

Re: Deploy Web Application

could you please explain how do i use the application

fyi

i am using the default iis services available on the windows xp system SP3

and i want to deploy the application in such a way that when the system is overloaded the application redirect the users to different server but when updating any information on the database it should get replicated on both servers i am really not good at this as this is the first time i have created a web application.. Please help

Re: Deploy Web Application

You probably would get better guidance on this subject over at the IIS forums since we don't cover advanced IIS configuration on the asp.net forums. They do have videos out there that teach how to use it and configure it.

Have you determined where your bottlenecks are? If the slowness comes from the database layer, adding multiple web servers will not help you.

I'm with Terri on this one. 80 or so users shouldn't cause the site to drag that much. What do your queries look like? Post them here if you can.

Re: Deploy Web Application

i'm sure its the database cause every combobox on the page is connected to a datasource and on a page there are around 10+ and how much of of difference will it make if the vb code is written on vb file rather than using vb script on the aspx page

Re: Deploy Web Application

Are you using AJAX? If so, that can cause web applications to suffer if the viewstate gets too large. The visual advantage of the screen not flickering between postbacks don't outweigh the increased loading times.

Re: Deploy Web Application

the usage of ajax toolkit is very high ....

Re: Deploy Web Application

To see the size of your viewstate, fire up Fiddler which can diagnose the communication between server and browser. Check your viewstate. If its larger than 100K, that is going to cause excessive drag in some instances. The key thing to remember is this problem will not present itself in development as there is no lag time between requests. However, you will see this behavior on production. One application I was working with (not my development) actually had a viewstate that was over 1 megabyte. I would hit my dropdown list, wait 15-20 seconds and then it would finally respond. You might want to use JQuery instead of AJAX with that many controls counting on the partial postback.
