Default Pathfinding Server Rollout

Pathfinding is rolling out on all regions today and will have an impact on the performance of your regions as well as introduce some new bugs.

Pathfinding & Region Performance
Once your region has been updated today, it will have Pathfinding running on it. Until your region has been optimized, this will have a performance impact. Linden Lab has assured me the impact will be at most 4ms on main regions and 1ms on homesteads. In layman's terms, this is around 18% of region performance. In order to optimize your region, you will need a viewer with pathfinding tools; currently these tools are only available in a LL Beta Viewer.

Your options will be to A) optimize your region; B) turn Pathfinding off on your region; or C) do nothing. Instructions for the first two options below...

Note: Only Region Owners and Estate Managers can work with Pathfinding.
Instructions to optimize your regions:
Download the LL Beta Viewer (Win, Mac, Linux) and go through the process of optimizing your region.

Turn Pathfinding off
1. Get sim console open.
Phoenix: Go to the top menu bar, Advanced > Consoles > Region Debug Console. (Press Ctrl-Alt-D to enable the Advanced menu if you do not already have it enabled.)
Firestorm: Go to the top menu bar, Develop > Consoles > Region Debug Console. (Press Ctrl-Alt-Q if you do not have Develop menu enabled.)

2. In the console window that opens, type (without the quotes), "set dynamic_pathfinding false", and press enter.

3. Restart your region.

Note: More information about Pathfinding can be found here:

New bugs you should be aware of!
Along with Pathfinding come changes to the Havok Physics engine, which have introduced some new bugs we think you should be aware of, including issues with some vehicles, physics, phantom and sculpts. You can view the list of issues we are aware of at the following link. None of these issues can be fixed by our support team:

Note: Unfortunately there are quite a few Linden JIRAs on this list that have been set hidden from public view. There is nothing we can do about that beyond offering a description of the issue.
Questions & Answers from Linden Lab
Yesterday I sent a list of questions off to LL and received the answers back this morning. These questions and answers may be of interest to you, as well, so I've put them online here.
