Six months ago we announced the beta test process of a new Second Life simulator, with the explicit goal of improving simulator stability. The new simulator went through six months of public beta testing, was in service on over 635 Second Life regions throughout the beta process, and during the public beta Early Adopter Program was found to dramatically reduce simulator crashes.
In addition to improving the Second Life experience by reducing the number of times a region is restarted (which forces all avatars off the region at the same time), lowered simulator crash rates also reduce content loss by reducing the number of times a region must be “rolled back”. Whenever a region is rolled back, any content changes since the last snapshot are lost, and the increased stability of the new simulator has likewise reduced the number of region rollback, and thus reduced the rollback content loss rate substantially.
Now that we have a week of active experience with the new simulator throughout Second Life, I thought it would be good to share the crash rate details so that you can see the impact of the Havok™4 project team’s work on increased simulator stability.
Below are two charts to show the stability improvement provided by the new simulator. The first chart shows the number of regions that crashed across all of Second Life, per day, due to physics engine crashes. Physics engine crashes were the most common cause of region crashes, and have been reduced by 97.2%
The second chart shows the number of regions that crashed from all crash causes. We also resolved some non-physics crashes during this project, resulting in a 68% reduction in region crash rates, across all of Second Life due to any cause.
We are continuing to resolve open issues with the new simulator, to make it even better both in terms of crash rate and functionality, and will be posting updates as this work is done.
Thanks again for all of your support and involvement,
Havok™4 Program Manager
