As we begin 2011, I want to share the progress that we’re making on several important technology enhancements that I discussed in my last post. As I mentioned, we are focused on improving the overall performance of Second Life while addressing some long standing limitations such as raising group limits, improving the chat system, and reducing lag.
Group Limits Raised to 42 Today
In October, we committed to increase group limits from the current 25 up to 40 in the first quarter of 2011. As of today, group limits have been raised to 42! To add groups beyond the previous limit of 25, you must be using Viewer 2.4 (or a more recent version). And if you’re still using Viewer 1.23, or a third-party viewer based on Viewer 1.23 code, then you can add more groups in Viewer 2.4 and they will still be accessible when you switch back to Viewer 1.23.
That said, if there is an unexpected load, then we may need to lower the group limitation to maintain acceptable performance levels across the grid. If we decide to do that, then any Residents who have up to 42 groups will not lose their memberships. But, other Residents will not be able to exceed the new limit.
Group Chat System Will Launch Gridwide By March 31st
We were set to deploy a prototype of the new group chat system in December, but last minute licensing issues were found with our chosen open source library. Now that a solution is in place, we expect to have the prototype available by the end of this month and an industry standard and high performing group chat system available by the end of this quarter.
Performance Improvements When Teleporting and Crossing Regions
As you teleport, or cross regions, all of your avatar data (often a very large amount of data) needs to be processed by both source and destination regions. In order to streamline this process, we are now compressing avatar information, making your teleports and region crossings faster and more reliable. In fact, we’ve found that teleport failures, due to avatar complexity, have dropped 40%. See the graph below for a more detailed view showing how much we’ve shortened region crossing time.
Viewer 2.5 Beta Releasing Soon
We will soon launch the latest version of the Second Life Viewer -- Viewer 2.5 Beta. In addition to more performance and stability improvements, we’ve added enhanced web-based profiles, accessible both on the web and in the Viewer. And, if you wish, you can even connect your Second Life profile to other social identities including Twitter, Facebook, and LinkedIn! You will also have the option in Preferences to choose your first inworld destination from the saved Landmarks in your Favorites Bar. This is very handy when you need to get to a specific destination quickly.
Also, one of the most important new features added to Viewer 2.4 was the auto-updater capability. If you're using Viewer 2.4 or higher, then you won’t be inconvenienced by the notification and download process when we release a new Viewer.
Planning to Implement Significant Grid Infrastructure Enhancements in 2011
We’re planning significant grid infrastructure enhancements throughout the year including technologies to speed server-side rendering (SSR) and server virtualization (web and simulator services). We are also exploring new storage and asset delivery systems. Some of the benefits will not always be noticeable, but they are foundational platform changes that set the stage for rapid performance and scalability improvements. We will continue to keep you updated as we roll out these systems.
I’m pleased with the progress that we made across the platform last year and I'm looking ahead to newer technologies that we will deploy in 2011 to enhance your Second Life experience. As always, I'll be watching for your feedback and thank you for making Second Life such an amazing place.
