DNN performance on IIs7

Well, it's an interesting thought. I couldn't tell from the control panel which mode the site was currently in, so I set it to classic. I will watch it for a few days to see how it goes. I have the site duplicated on my local dev server using the database from discountasp, the local site starts up much faster. I t really looks like just not enought resources. I am looking closely at semi dedicated vps plans to get the extra resources that shared hosting does not offer...

Hi Henry,
Please keep us posted.

I don't have anything to report other than I've seen many times in Blogs that DNN on IIS7works bestin Classic mode.
i.e. http://www.snowball.be/DNN+And+IIS7+How+To+Get+It+To+Work.aspx

You can switch to Classic Mode in your Control Panel.

I'm not suggesting you need to, only that you may want to try it.
Salute,

Hi Mark,
I' ve seen all DNN sites from http://www.janetsystems.co.uk/Clients/ClientDirectory/tabid/68/Default.aspxbut didn't impress me. Can you give a DNN site which impress you?

Anyone have any success getting Dot Net Nuke to perform on IIs7 as well asd it does on IIs6?

We have a site here using Server 2008 and IIs7 and the site acts like it's choking for resources to run correctly. Same code base and version (4.8.2)m seems to run ok on IIs6 on other host...

Appreciate any suggestions

Here is a performance graph of the site I am hosting here. Every hour it shows the performance drops to more than 12 seconds to reload. I monitored 2 other sites on another hoster and only saw 2 dips in load performance during the same period. I have sent this to support, I hope they will look into this...

I don't know of any but will keep an eye open.
For the most part DNN is by itself both impressivebut rather resource heavy.
I've helped many accounts here setup versions of DNN and add modules.
You get a lot but you do pay the price.

Reminds me of a conversation with my 9 year old son.
He always asks if we can drop my custom Harley engines on one of his bicycles.
I tell him sure, but it will break the frame.

 

Your application pool is probably recycling, which causes a longer initial load as the application has tore-compile after it is purged from memory.

You can see that effect yourself by going in to Control Panel and recycling the application pool then hitting your site.

 

I suppose that is exactly the issue. I am hitting the site every 6 minutes, the application pool should not be resetting. There should NOT be any lag in performance. I am testing other sites which are hosted on win 2003 and IIs6, same codebase, just a few users and very little modules installed and used, and I am not seeing this poor of performance on other sites monitored.


I realize that there is an invested interest to find the fault with the client, the client code or some other network infrastructure issue not related to the hosting environment, but I am not making this up, and it benefits everyone to find, diagnose and cure problems. Windows Server 2008, IIs7 are both new technologies, and for my 2 cents are currently not proven technology meriting adoption...





And, allthough I am not posting the graph here today, it is remarkably like yesterdays, 8 or 9 good response, and then a slow response at almost 1 hour intervals.

Well I suppose you could say that about any new O/S release, not just Windows, but of course we still offer Windows 2003/IIS 6 hosting. Though if I remember the numbers correctly from the last meeting where this issue was discussed, 30 - 40% of new accounts are choosing Windows 2008/IIS 7.

As for having a vested interest in finding fault with things outside our network, I can see how someone might get that idea. The problem is, the vast majority of time, it is a problem outside of our control. So what happens is if you say that over and over enough times (when it happens to be true), after a while you start to look like an apologist.

But when you see the same problem hundreds of times, it becomes routine to offer up the typical solution. The answer is almost always right. Sometimes it is not. But it's like the old saying, "when you hear hoof beats you don't think of zebras" (I think I used that someplace else around here -- I promise I won't use it again ). Meaning, of course, thatyou don't immediately offer up the most obscure and unlikely response to a common question.

I don't know of any hourly process (on the IIS 6 or IIS 7 servers) that would force all the applications on the server to recycle. But I will ask around.

 

By the way, I don't understand your graph...the time points seem to repeat:

6/14 12AM --6/15 12AM --6/15 12AM --6/15 12AM --6/15 12AM --6/15 12AM --6/15 12AM

So it's difficult totell what the real time frame is...

 

That is an error withing the graphing setup, that iswhy Ispecifically state that the graph represents a certain time frame and the last entry is xx time. Altholugh the image does not show the right time the text log does...





Hope that clarifies this...





Henry

 

I get that it is every hour, but at what point during the hour? On the hour? 18 minutes past? It would help to know specifically.

 

In the graph, there is a little "tick" mark. That tick signifies every 10th test. since the tests are approx each 6 minutes, you may interpet the results from there. The service that produces the graph is located at keepaliveforever.com.





Henry

 

sorry, I think I answered the wrong question, the service provides a text log, one might be able to nail down an exact time from that. The problem will always be that not everyone is on the same exact time..
