This is the meeting tracking and progress page for the weekly Server BETA QA Meeting, moderated by Maestro Linden. Please contact him on AGNI for more information. You can join the Second Life Beta group for updates.
The next meeting is Thursday, October 9 2014, 3PM PDT at Morris🖈 on the preview grid, ADITI.
Agenda
Updates
- The main channel got the maintenance project which was previously on all three RCs
- Release_Notes/Second_Life_Server/14#14.09.26.294825
- It fixes a bug related to viewing parcel details in skill gaming regions
- No rolls for RC BlueSteel, RC LeTigre, or RC Magnum is getting the same update as BlueSteel and LeTigre.
- RC Snack still has the CDN #Texture And Mesh Fetch Testing project
- This week's update was to include the changes that went to the main channel
- Release_Notes/Second_Life_RC_Snack/14#14.10.03.295112
- The channel has grown to ~270 regions total now, mostly mainland
- If you own a region and would like to have it moved to the RC Snack channel for CDN testing, please email cdn-test@lindenlab.com
- Simon's group chat changes is now in the process of being deployed
- We expect it to be fully out by sometime next week
Texture And Mesh Fetch Testing
- A new texture/mesh asset fetching service is up on Agni and Aditi for testing
- No special viewer support required (works with the Second Life 3.7.14 release viewer
- Sims which use this service have the viewer fetch meshes and textures from a CDN, rather than through the sim host
- This is accomplished by changing the URLs the viewer receives for GetMesh, GetMesh2, and GetTexture capabilities
- Rather than getting a capability URL like https://sim9672.aditi.lindenlab.com:12043/cap/d8524a49-57f2-e73e-51d2-85148edb1fc1, the viewer gets a capability URL like http://asset-cdn.aditi.lindenlab.com/
- The advantage of this approach is twofold
- The sim isn’t burdened with texture and mesh asset requests
- The CDN is globally distributed, so viewers located far away from the sim host will enjoy faster speeds (due to lower latency) when fetching these assets
- This service is live on Agni now, in the “Second Life RC Snack” channel
- A few privately-owned regions are on this RC
- A few Linden-owned regions are also on this RC
- Denby
- Hippo Hollow
- Hippotropolis
- Testylvania Sandbox
- This service is live on Aditi now, in the “DRTSIM-258” channel
- Region “TextureTest CDN” on DRTSIM-258 contains about 5650 textures to download, when viewed from the parcel TP location with 512m draw distance
- Region “MeshTest2H” on DRTSIM-258 contains about 5170 meshes to download, when viewed from the parcel TP location with 512m draw distance
- For comparison, regions “MeshTest2” and “TextureTest SLS” on the “Second Life Server” channel have the same content but use the ‘classic’ asset fetching method
- Performance results thus far
- Maestro and April ran some benchmarks from the office
- In the mesh test regions,
- On DRTSIM-258 (using the CDN), all the meshes are fetched very consistently, within ~51 seconds
- On SLS (not using the CDN), mesh fetch time averages ~78 seconds, with varied results
- In the texture test regions,
- On DRTSIM-258 (using the CDN), texture fetch time is about 43 seconds
- On SLS (not using the CDN), texture fetch time is about 105 seconds
- In the mesh test regions,
- Early results from Europe are also very promising (appear to show about a 2x speedup in loading time with the CDN, compared to without)
- Recommended test setup
- Clear cache prior to test (deleting the viewer’s cache folder is a pretty convenient method)
- Do a preliminary run before benchmarking to 'warm' the cache (applies to both CDN and simhost texture fetching)
- Login directly to the test region
- No other avatars around
- Draw distance set to 512m
- Maximum bandwidth set to 10000kbps
- Viewer always kept in focus (otherwise FPS is capped at ~20fps, possibly affecting fetch performance)
- Don’t touch the camera
- For mesh benchmarking, we used the 'Mesh Download Quiescent' message in the viewer log. This message triggers when the viewer has fetched all the meshes it wants, and prints the fetch start and stop times (used to compute duration)
- For texture benchmarking, we used time from hitting the ‘login’ button until the time until the texture console (Develop -> Consoles -> Texture Console) indicated that 0 textures were remaining to be fetched, with “Fetch 0(0)”
- Because of the delay involved when logging in, this texture fetch benchmark is much less precise than what we have for meshes
- Maestro and April ran some benchmarks from the office
- Feel free to try it for yourselves! (please be gentle..)
Interesting Stuff
- Let's do a group chat test!
