Landing page download times

To anyone that can help!

I have a website running in development environment on two seperate server(s). One on my personal server and another on DiscountASP hosting environment. I'm getting very slow speeds when accessing the landing page for example URL http://www.domain.com/default.aspx.

It takes between 10 - 15 seconds to load. The default.aspx page holds few controls and web parts and has 2 images plus 2/3 paragraphs of text. Once this home page loads the remainder child page requests run fast. Any ideas why this would occur? Also once site landing page is cached it runs fast as expected!

Any help would be greatly appreciated.

Kind regards,

Sahus Pilwal

RE:Landing page download times

Hi,

The problem can be also caused by the hosting environment restrictions - I am aware that DiscountASP has restrictions on CPU and Memory usage and also on idle time. The application is then killed, so the first start takes more then usual. Could you please check the event log in Site Manager -> Administration? You should see there Application_End and Application_Start events.

Hi Jurajo,

I see lots of references to Application_Start and Application_End every 15 mins or so in the event log.

Here is the content of the log:

Event ID: 762

at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback(Object state)

I also received this slow load when it was hosted on my own development server so not sure if this is the problem. Do you know of any methods to optimise the speed of the website. I also got a report done from website speed testing tool. It came back stating the site was loading in 0.9 - 1.7 seconds. Though I've found it to take anything from 3 - 10 seconds loading from my own browsers.

Any help would be greatly appreciated.

All the best,

Sahus Pilwal

Can be this the issue? Moreover, here you can find more information about performance - http://devnet.kentico.com/Blogs/Martin-Hejtmanek/August-2008/Performance-of-Kentico-CMS.aspx Best Regards, Juraj Ondrus

RE:Landing page download times

Hi Jurajo,

Yes it's restarting the application every 20 minutes. I'm sure this is causing the problem as the website has to re-compile serverside code into the asp.net runtime engine before it returns the code to the client. This would occur anytime the IIS or website application restarts. As this occurs every 20 minutes it seems the site landing page is always slow. That's not the case. It's because it's re-compiling everytime which is normal behaviour.

Do you think DiscountASP are doing this for a reason relating to the CMS solution. Can I prevent them restarting the application or request them to stop this restart of web app? Would it be worth uploading the default corporate site and see if this occurs also. This could enlimate the problem being with the CMS solution or just the website package?

Any help would be greatly appreciated.

All the best,

Sahus

RE:Landing page download times

Hi,

These are the default settings for all applications hosted on DiscountASP. We do not know why they have these restrictions.

I do not know if they will change the setting for you. Anyway, I would like to recommend you Applied Innovations hosting - http://www.kentico.com/Partners/Hosting-Partners.aspx
