2023 SL SUG meetings week #39 summary

The Enchanted Library, July 2023 – blog post

The following notes were taken from the Tuesday, September 26th Simulator User Group (SUG) meeting. They form a summary of the items discussed and is not intended to be a full transcript. A video of the entire meeting is embedded at the end of the article for those wishing to review the meeting in full – my thanks to Pantera for recording it.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas.
  • These meetings are conducted (as a rule):
  • They are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Server Deployments

  • On Tuesday, September 26th, simhosts on the SLS Main channel were restarted without any code update.
  • On Wednesday, September 27th, the RC channels will be similarly restarted without any change to the simulator version.

Viewer Updates

No updates to the official SL viewers at the start of the week, leaving the current list as:

Region Crossing Code Tests

Maestro Linden is leading work on trying to improve avatar arrival performance during regions crossings. As we all know, avatars entering a region that is busy / active with other avatars, can have an impact on simulator performance – which although not as bad as it once was thanks to an earlier tranche of this work a few years ago, is still a problem. The aim of this work is to smooth things even further, initially for the case of teleports, but later with direct / vehicle crossings.

As a part of this work, two regions have been opened on Agni – Arrival Terminal 1 and Arrival Terminal 2, each with a different configuration for handling avatar teleport arrivals. These were used through the greater part of the meeting for qualitative and comparative testing with controlled (and monitored) group teleports from regions with the current teleport protocol and directly back and forth between the two, with LL gathering up the resultant logs for review.

Following the session, Maestro indicated that further testing may take place at the next SUG testing, and the two regions may be places adjacent to one another to allow for testing physical crossing / vehicle crossings between them.

In Brief

  • Leviathan Linden is continuing to work on game controller integration with SL, but outside of having some issues in getting some buttons to recognise / be recognised by SL when using the SDL2 API.
  • Rider Linden is now in the midst of “a rather large refactor that should modernise how the simulators handle HTTP connections (both internally and with the outside world.”
  • A brief, general discussion on LSL, the Mono bytecode interpreter and its ability to potentially allow the use of other languages (e.g. C#) on top of it by having it call native functions in the selected language.

† The header images included in these summaries are not intended to represent anything discussed at the meetings; they are simply here to avoid a repeated image of a rooftop of people every week. They are taken from my list of region visits, with a link to the post for those interested.
