We have updated and expanded the Second Life Service Quality Metrics page through the end of September 2007, and as promised, we’re including the Viewer and Region crashrates and performance statistics on that site instead of in the Economy metrics where we temporarily posted them in July.
Highlights of the new data include 3 monthly charts as well as detailed data at a Daily level from Jan through September 2007 in Excel, OpenDocument, and Google Doc formats. One interesting addition to these data file formats is metadata in the headers – click on the report titles or field titles to be hyperlinked to the data’s business definition on our Metrics Glossary wiki page.
The overall Service Availability chart shows a serious improvement (decrease) in Unplanned Outages for September. We are also working to reduce the impact of our Planned Outages and look forward to keeping the level of Unplanned outages down consistently over time, as Ian discussed in his blog post on availability.
Each of the 3 new charts represents a subject area that Linden Lab is focusing on improving. Viewer Session crashes are being improved first by focusing on Region Sessions terminated, which will be reduced along with Region crashes. The Havok4 project as well as several other projects should help significantly with those. The client-side crashes are also being addressed, and recent updates to our Viewer and Region code are improving the error logging so that we can focus on the most significant sources of those crashes.
Viewer performance in average Frames Per Second (FPS) benefited most this year from our Pipeline changes in April, and residents who are experiencing poor client FPS can most benefit from ensuring they are using at least Minimum Supported hardware. More information will be forthcoming about the average FPS for the graphics cards you are using, which will clearly demonstrate that the unsupported cards are the source of the poorest user experience and highest “lag”.
Region performance in FPS is one area we have been focusing on closely. The Havok4 engine should help improve and stabilize this environment, and other Linden Lab developers have found other system improvements to bring these figures up before the Havok change, so you should expect to see some improvements in the October figures. If you are a private estate owner interested in managing your own region’s FPS, you can get more information at our new Region Performance Improvement Guide wiki page.
Thanks for everyone’s attention, and we be back with more Service Quality Metrics improvements next month.
