As I mentioned in my previous post, the site was bottlenecked by having the Apache/PHP and MySQL servers on two separate machines. This is the standard setup at Dreamhost; even if you have a PS, the mysql part is hosted on a different server. So even if you don't have to share a machine with other websites hosted on Dreamhost, you're still sharing their network latency when the Apache/PHP server is communicating with the MySQL server. On a typical non-cached page, the IVRPA site makes 200-400 queries to the database.
The reason why I have been quite busy lately was this:
My company produced this exposition for Palmela Castle about the history of the place from the middle age until present and this will be on display at St. James Church in Palmela Castle until summer 2010.
It involved working long ours for about a week and my team responded very well and we managed to get everything ready in time in the inauguration day.

Since the migration, the site has been having performance issues. While I had hoped that the site perfromed better with a newer version of Drupal, we're actually seeing worse performance.
The IVRPA website is undergoing major maintenance work. We are updating our data structures in the process. Read the announcement for more information.
During the migration, the site is in a "read-only" state; you can not log in to the site to post content and/or make changes to your profile etc. The IVRPA mailinglist remain active. In this post, I will keep track of the progress of the actual migration.

I'm generally quite happy with the site here at Dreamhost. Even so, every now and then, the site(s) become(s) unresponsive and goes down. We're being told that our site was using up a lot of memory, which crashed the (private) server. After a reboot, most of the time the site works fine again.
It's been a bit silent, but that does not mean nothing has been going on ;-)
Yesterday, Matthias announced the website for panoramas and still images shot at the IAPP/IVRPA Alburquerque Balloon Fiesta. In the next few days, that site should be filling up with some nice panoramas shot by the IVRPA members attending the fiesta. It looks like a great event for VR panoramas.
The 2009 Albuquerque Balloon Fiesta Photo Safari is SOLD OUT.
We are happy that many IVRPA members are joining us for 5 days of running around between shooting hot air balloons at 4:00am in the morning, watching the talks at Plaza Inn Hotel conference room during the day and socialize during the scheduled nightly events!
The speaker list will be announced soon, and many IVRPA members will be featured speakers showing that indeed the IVRPA is alive and kicking, we thank those who offered to be speakers in this event noting that this is a volunteer action that we appreciate.
What panorama players are available? How does the choice of player affect the way a panorama performs? Is the image rendered differently? How long does it take to load? These examples show over a dozen different panorama players, each using basic settings and copies of the same source images, to help find answers to questions such as these.
The panorama players shown here include the venerable (but possibly fading) QuickTime VR itself, a number of Flash and Java-based players (well-known and otherwise), Shockwave, a couple of entirely custom-coded engines, and one that uses Microsoft's Silverlight platform. Among these are the best in the panorama industry, although it is up to you to decide which those are.
The village is located near the river Rhine and is first mentioned
in the history in 745 and is about an hour drive from Frankfurt.
The file structure of the tour consists of the executable Silverlight
component (25KB), the configuration file and the tour data of 41 panoramic
images in JPEG with 4000px x 2000px each (1MB).
