I've been tasked with looking into performance tuning my company's intranet server. It runs DotNetNuke which suffers from poor performance. It also runs a number of other web apps (mix of asp and asp.net).
Could anybody give me a brief list of common performance tweaks that can be made to IIS6?
Last night I did a load test on a site. I found that one of my shared caches is a bottleneck. I'm using a ReaderWriterLockSlim to control the updates of the data. Unfortunately at one point there are ~200 requests trying to update the data at approximately the same time. This also coincided with CPU usage spikes.
The data being updated is in the ASP.NET Cache. What I'd like to do is if the CPU usage is around 75%, I'd like to just skip the cache and hit the database on another machine.
My problem is that I don't know how expensive it is to create a new performance counter to check the cpu usage. Also, if I would probably like the average cpu usage over the last 2 or 3 seconds. However, I can't sit there and calculate the cpu time as that would take longer than it's taking to update the cache currently.
Is there an easy way to get the average CPU usage? Are there any drawbacks to this?
I'm also considering totaling the wait count for the lock and then at a certain threshold switch over to the database. The concern I had with this approach would be that changing hardware might allow more locks with less of a strain on the system. And also finding the right balance for the threshold would be cumbersome and it doesn't take into account any other load on the machine. But it's a simple approach, and simple is 99% of the time better.
I have database with 40 big tables.In each stored procedure query is containing minimum 6 joins.The query is taking too much time to execute.I didn't implemented views and indexes.
View 2 RepliesI 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 am creating a service oriented application where trying to have everything using services....however there is something I am not sure of , I am having a page that calls the database at the page load...so what would be better and faster?? to call database in pageload , or to call wcf service from javascript during javascript load ??btw , I am using a repeater in the page , but I have created somekind of an engine to create the suitable html so...I'll be creating the repeaters html using the wcf and resend it back to the page If I am using a wcf service at the start.

I'm using DotNetNuke 4.8.x and want to utilize jQuery. Could anyone possibly suggest me on what is the best way to integrate jQuery into DNN? I won't be able to upgrade DNN version to 5 which has built-in support for jQuery.
View 1 RepliesCan anyone shed some light on why DotNetNuke comes configured with request validation and event validation disabled? They're both off at the web.config level for a default install which seems to be a regressive approach. Are there any sound reasons for this and what is the functional impact on DotNetNuke if they're turned back on?
Obviously appropriate input validation should be happening in code anyway but the native .NET framework behaviour is always a nice fallback.
We are in the process of implementing a CMS for our project which currently extensively uses asp.net master pages and css. Also the application is data-driven and controls like gridview and listview are used. After a little search we zeroed on two CMS dotnetnuke and umbraco. Now my question is:
Which one of the two CMS is best suited and easy to use?
Do they support integration of existing code and UI's

I want to create a new module in DNN (VB) ... that;
1. does not use DAL or DAL+
2. has only one view.ascx control
3. It has to be a compiled module
I do not need DB connectivity and any bells and whistles just one view control. I thought it would be simple but googling for a day now and it seems very complicated.
I have the development environment already set up with;
1. DNN Starter kit
2. VS 2008
3. SQL server
4. DNN up and running in IIS
5. the project builds successfully
If anyone knows a way I can build a module using the DNN Dynamic Module Template in VS 2008 and then strip off the DAL and all the unnecessary layers and extra controls until I have only a working view.ascx that just prints out "Hello World!" to the screen ...
I am getting started with DotNetNuke and when I try to use jQuery the same way I use it in any standard ASP.NET page it does not work. For example I am trying to use uploadify which uses jQuery and flash. I can't even get the cancel button to show in the control.
By now I understand there must be a workaround and it is different than simple asp.net
Here is the ascx code:

I've Googled, Binged, and here at StackOverflow, looked through the related questions and searched, but I'm not finding what I'm looking for. I've also searched documentation on DNN.
What I'm looking for is any guidance (tutorials, blogs, step-by-step instructions for setting up a repository) etc from people who are experienced in using DotNetNuke with SVN.
We use SVN for all our source control, and have no problem with standard applications, because we pretty much built the repository and directory structure to work with our processes. This means when we do web sites, in Visual Studio, we do file based web sites, rather than setting them up in the local IIS. It just makes things easier for us.
However, with DNN, it appears that even if you get the source code, it is expecting to be set up in the local IIS, which means additional headaches for us.
For example, we are moving all of our source code off our local C drives, and onto a shared drive on a server. This is to enable backups in addition to our normal source control. (This was a management decision). So that means that we need to change the virtual web app when we make the move.
Has anyone come up with a good way to work around this? Can DNN be set up so that the developer web server in Visual Studio can be used, so that we can treat it just like any normal web app? Am I missing something obvious?
I'm creating a new DotNetNuke module and in the past I inherited from PortalModuleBase. I'm aware that there's a replacement for this now. Can someone tell me what it is? I've had a brief search for it but I haven't found what it is.

In dotnetnuke, I have two sites located on different location. Now I want to point these two sites to the same database. Is it possible to point to same database.
I even tried pointing it from web.config, but thats not working. I don't want to work with child portals, because i have already created site on other location and all the source codes are under that, but when I create child Portal, it creates new portalnumber folder under portals, and it just has two folders in it, Users and Cache, I dont understand how to place codes, as DNN creates lots of folders while creating new site, which are missing here.
I want to create a module that can send a message to another module in different tab.I don't know the target tab Id but I know the target module name. Is there any way to do such a thing?Is Dot net nuke support messaging?

View 1 RepliesAs part of a redesign for one of my clients I'd like to move them to DotNetNuke to gain the CMS and blogging features. Their existing site has some custom ecommerce functionality that an off-the-shelf package just can't handle, so I'm inclined to leave it and just re-skin to match the new site.
The challenge is making this all fit together.
I could create two physical web sites in IIS, for example:
www.website.com <-- DNN install
and
shop.website.com <-- Existing ecommerce
This would keep things isolated, but I see a problem with the SSL certificate. It's tied to www.website.com, so now I'd either need two -- one for www. and one for shop. -- or I need a wildcard certificate. Either adds ongoing expenses for the client.
I could try to encapsulate the existing site into a DNN module, but that seems like a lot of work. I could also try doing something tricky with iframes, but again I think this would just further complicate things.
When user clicks on linkButton it needs to open new window to display some data. I try this:
string url = "~/SomePage.aspx";
string cmd = "window.open('" + url + "', '_blank', 'height=500,width=800,status=yes,toolbar=no,menubar=no,location=yes,scrollbars=yes,resizable=no,titlebar=no' );";
ScriptManager.RegisterStartupScript(this, this.GetType(), "newWindow", cmd, true);
But it doesn't work. I can't even manually navigate to this page. Opening new window work but it opens the same page in that new window. So, how to display content from SomePage.aspx in this new window?

I am moving a site from one godaddy account to another godaddy account. Same ASP.NET 4 IIS 7 settings.
What I notice is that all the friendly urls like home.aspx _login.aspx_ return a 404 ERROR, as if the rewrite was not working. As a desperate attempt, I switched from urlFormat="humanfriendly" to urlFormat="searchfriendly" and it started working. But humanfriendly, that allows short and clean urls won't work at all.
