CATALooK Skins

The CATALooK skins without image backgrounds (theme-grey, blue-2d.ZIP, blue-2d_small.ZIP, blue-metal.ZIP, blue-metal_small.ZIP, compact-grey and spreadsheet-grey) will load faster than the standard blue or the classic-blue/ classic-purple skins.

Viewstate

More than 50% of all DNN site content is Viewstate. To remove the Viewstate from the site content, you can install a Viewstate remover. There are several modules available for that: e.g.:  Open-ViewState 2.0 Price: $9.75  http://www.snowcovered.com/snowcovered2/Default.aspx?tabid=242&PackageID=3602

This will reduce the site loading time up to 50%.

Cache

Some hosting providers unload the DNN dll's after a certain time to save CPU time on their shared hosting environments. Also DNN deletes the cache after a certain time. This can be bypassed by SmarterPing by SmarterTools.

SmarterPing by SmarterTools keeps DNN sites up and running and it does a great job. If you ping DNN URLs it dramatically improves the performance of DNN. Set SmarterPing to ping 4 or 5 key areas every minute.  The load times are 4 or 5 times faster.
