+\# Cortex JIT Benchmark Suite
+
+
+
+This directory contains benchmarks to evaluate the impact of
+
+Python 3.13's experimental JIT compiler on Cortex operations.
+
+
+
+\## Benchmarks Included
+
+
+
+1\. CLI Startup Time  
+
+   Measures cold start time of the `cortex` CLI.
+
+
+
+2\. Command Parsing  
+
+   Benchmarks argparse-based command parsing overhead.
+
+
+
+3\. Cache-like Operations  
+
+   Simulates dictionary-heavy workloads similar to internal caching.
+
+
+
+4\. Streaming  
+
+   Measures generator and iteration performance.
+
+
+
+\## How to Run
+
+
+
+From this directory:
+
+
+
+PYTHON\_JIT=0 python run\_benchmarks.py  
+
+PYTHON\_JIT=1 python run\_benchmarks.py  
+
+
+
+Or simply:
+
+
+
+python run\_benchmarks.py
+
+
+
+\## Findings
+
+
+
+Python 3.13 JIT shows measurable improvements in:
+
+\- Command parsing
+
+\- Cache-like workloads
+
+
+
+Streaming and startup times show minimal change, which is expected.
+
+
+
+These results suggest Python JIT provides benefits for hot-path
+
+operations used by Cortex.
