Hi,
I've built a site (www.saileasy.com) with DNN, the commercial module ListX and PageBlaster and Minimalist O'Neil skin, on WH4L.

Everything is ok except for the loading time of the page. I've used HTTP Watcher to analyze the loading time and I've noticed that the most time is related to the skin images (aprox 12 sec for the home page).

Is it a hosting provider issues ? Have you do something in your experience?

Thanks
Vincenzo

Are you referring to an initial load of the page, or any load?

IIS's standard configuration unloads websites after 20 minutes of inactivity. Most of use use a "keep alive" service or application to keep the site loaded.

You should also review your installation's performance settings. John Mitchell (snapsis.com) offers these as the preferred settings:

"If you are not using PageBlaster then I would recommend setting the performance settings as follows:

Page State Persistence: Page
You could try memory, but I believe there are too many problems here without much gain especially as a global setting.

Module Caching Method: Memory
Memory is much faster, and there are intermittent errors when using Disk.

Performance Setting: Heavy
There is really not much difference between the different settings here. The setting is just a multiplier that gives you only 5 hours of caching at the most (depending on the object) when on Heavy. Some items are not cached at all unless you are on Heavy.

Authenticated Cacheability: Set it to public.
This allows the client browser or downstream proxies to cache items.

Compression Setting: Deflate or Gzip does not matter.
They are both about the same and will vary depending on content. I use Gzip.

Compression Level: There is a bug that is keeping it from being applied, but it should be around five, higher than that gives diminishing return.

Use Whitespace Filter:Not Checked
Don't use it if you have compression on it is a waste of time, because compression also removes white space."

on the home page, if you look at the images in the right pane 'Le Barche piu' Viste'

those images are around 17kb each - for that size image you could probably reduce the file size which would help to speed up load times.

Have a look at this page for free keep alive services

It could be related to the use uf resx file to localize the portal.

I'm thinking about that because I've noticed on Localhost on which I've built a second portal that the last is very quick respect the previous one. The mail difference is that is not thinking to use in a multilanguage environmente so i don't use resx file.

Thanks,
Vincenzo
