⚡️ Speed up function `extract_sentrytrace_data` by 37%

Open misrasaurabh1 opened this issue 2 months ago • 0 comments

📄 37% (0.37x) speedup for `extract_sentrytrace_data` in `sentry_sdk/tracing_utils.py`

This one looked really important as well. I found a bunch more optimizations, but don't want to spam you guys. Would you like to meet over a 30 min call to discuss how we can better coordinate?

⏱️ Runtime : 3.30 milliseconds → 2.41 milliseconds (best of 124 runs)

📝 Explanation and details

The optimization adds length checks before expensive string formatting operations. Specifically:

Key Changes:

Added len(trace_id) != 32 check before "{:032x}".format(int(trace_id, 16))
Added len(parent_span_id) != 16 check before "{:016x}".format(int(parent_span_id, 16))

Why It's Faster: The original code always performed string-to-int conversion and formatting, even when the trace_id/span_id were already properly formatted. The optimization skips these expensive operations when the strings are already the correct length (32 hex chars for trace_id, 16 for span_id).

The int(trace_id, 16) and "{:032x}".format() operations are computationally expensive, involving:

Hexadecimal string parsing
Integer conversion
String formatting with zero-padding

Performance Impact: Test results show the optimization is most effective when trace IDs and span IDs are already properly formatted (which is common in production). Cases like test_valid_full_header show 51.6% speedup, and test_missing_trace_id shows 65.9% speedup. The optimization has minimal overhead for cases where formatting is still needed, with only small gains (1-7%) for malformed inputs.

This is particularly valuable for high-throughput tracing scenarios where most headers contain well-formatted trace data.
