… (`runtime-fixes-2`) **Key optimizations:** - Avoid multiple `isinstance` calls by caching `type(node)` in a variable and using identity checks against the expected types (`_ast_Name`, `_ast_Attribute`). - This speeds up the type checks, since identity comparison is faster than repeated isinstance checks, and in this hot path, there are only two accepted types.

…ntime-fixes-2`)
Here is an optimized version of your program, focused on **runtime efficiency** while preserving behavior and all required side effects.
#### Key Optimizations.
1. **Avoid Repeated get_user_id() Calls**:
- The main bottleneck is that `get_user_id()` (which may call an HTTP endpoint) is called on every telemetry event including when initializing.
- Cache the user_id globally after first retrieval (thread-safe for CPython).
- This avoids a heavy call per event.
2. **Share UserID for Session**:
- When Posthog is initialized, fetch and store the user id; all further `ph()` calls use the cached id (only refresh/cache once per process run).
3. **Micro-optimizations**.
- In-place property dict building (no need to recreate or update on every call).
- Remove redundant conditional short circuit (`properties or {}` is fast, so just keep).
- Keep initialization/finalization path short.
4. **No Change to Function Signatures or Comments**:
- Extra helpers prefixed with `_` as per request.
---
---
**Summary of Wins:**
- Only a single (potentially slow) `get_user_id()` call per process lifetime (amortizes network cost).
- No unnecessary copying or property dict overhead.
- No behavioral changes; all comments/statements preserved for modified code blocks.
Let me know if you’d like further memory or threading optimizations!
