From the LL-origin inefficiency audit (finding A5). File/line references are from commit 0229f8872c; re-locate them before working.

Pose blender

  • std::list mActiveBlenders node per joint per frame (llpose.h:152, llpose.cpp:553)
  • unordered_map lookup per joint state (:536)
  • unused ~1 KB LLJoint mJointCache per blender (llpose.h:144, only for the dead time-quantum path)
  • refcount churn in addJointState/clear (llpose.cpp:246-255)
  • Fix: flat array by getJointNum(); reserved vector; drop the cache.
  • Confirmed. M.

Verify the cost (profile or timer) before and after changing it.

File/line references are from commit 0229f8872c; re-locate them before working. **Pose blender** - `std::list` `mActiveBlenders` node per joint per frame (`llpose.h:152`, `llpose.cpp:553`) - `unordered_map` lookup per joint state (`:536`) - unused ~1 KB `LLJoint mJointCache` per blender (`llpose.h:144`, only for the dead time-quantum path) - refcount churn in `addJointState`/`clear` (`llpose.cpp:246-255`) - **Fix:** flat array by `getJointNum()`; reserved vector; drop the cache. - Confirmed. M. Verify the cost (profile or timer) before and after changing it.
