    We upgraded to a newer version of DotNetNuke about a week and a half ago, this caused a couple of performance related issues with the site. I've spent today trying to iron some of those out, though it looks like there may be a few more bugs to squash.

    I made some changes to the look of the top portion of the pages. The Search, Login and Register links (when not logged in) are now below the Logo and the yellow banner area, instead of up at the top where they were easily lost in browser tool bars.

    You will also notice a new look for the Notifications and Messages that the latest release of DNN brought along. We'll have more changes over the next couple of weeks as we implement new features on the site

    When I verify pages, there are four warnings and one error:
    Warnings:
    * threads: Resource interpreted as Image but transferred with MIME content text/html
    * placement.js: Resource interpreted as Script but transferred with MIME content text/html
    * 600: Resource interpreted as Document but transferred with MIME content image/gif
    * adview: Resource interpreted as Image but transferred with MIME content text/html
    * threads: Resource interpreted as Image but transferred with MIME content text/html
    Errors:

Domains, protocols and ports must match.

    There are a BUNCH of things (OK, 11) tagged in a profile of loading a forum page. Nine of those reduce network bandwidth, two are page rendering performance improvements:
    * Combine external CSS (6)
    There are multiple resources served from same domain. Consider combining them into as few files as possible.
    6 CSS resources served from http://www.sccaforums.com">http://www.sccaforums.com">http://www.sccaforums.com">http://www.sccaforums.com">www.sccaforums.com.
    Combine external JavaScript (23)

    8 JavaScript resources served from pagead2.googlesyndication.com.
    * Enable gzip compression (4)
    Compressing the following resources with gzip could reduce their transfer size by about two thirds (~3.05KB):
    placeholder-3649861 could save ~720B
    placement.js could save ~898B
    placeholder-5403363 could save ~1.02KB
    7474-142431-17922-1 could save ~467B
    * Leverage browser caching (101)
    The following resources are missing a cache expiration. Resources that do not specify an expiration may not be cached by browsers:
    addthis_widget.js
    The following cacheable resources have a short freshness lifetime:

    Unfortunately those errors are the least of the problems right now :)

    Something keeps hogging up database connections and then starts causing timeouts. I'm trying to figure out what that is.

    Thank you Virgina America for having in flight wifi

    Made some additional changes tonight (software upgrade) and turned the friendly URLs on again. Hoping that things work a little better than they have the past couple weeks. If you run into slowness or performance issues please let me know.
