11.05.11.229574

• Kelly's "mono2performance" project. deployed 2011-05-12
  • Script performance and robustness

    This release includes many features that improve the performance and robustness of scripts compiled to Mono. This includes a lot of back end infrastructure work with unit tests and script life cycle to make it easier and safer to work with the script system in the future.

  • New Script Profiling LSL Functions
    • llScriptProfiler can enable or disable memory profiling with PROFILE_SCRIPT_MEMORY and PROFILE_SCRIPT_NONE. While profiling the scripts performance will be severely impacted.
    • llGetSPMaxMemory will report the highest level of used memory during the most recent, or current, profiling run.
    • llGetUsedMemory will report the current used memory of the script and does not require profiling to be enabled.
  • Bug Fixes
    • SVC-3895 Rezzing Mono scripted object cripples sim FPS
    • Improved 'Top Scripts' report

      Each object now reports an average script time per frame since the object was created or the last 30 minutes, whichever is shorter. This fixes a lot of odd behavior and misinformation in the previous results as well as makes it easier to determine recent lag sources instead of only immediate lag sources.

      It is still not expected for this result to exactly match the 'Script ms' reported in the simulator stats summary as these measure different things on different time scales.

    • (Fixed a) Sim crash in mono memory monitor.
    • Includes the fix that caused the zero day rollback.
  • New Bug Fixes
    • Improved simulator performance when removing objects with scripts from a region.
    • Fixed a bug that could cause scripts to crash with NullReferenceException errors.
