⚡ Bolt: Optimize vm_stat parsing in metrics tracker - #2
Conversation
Optimized the memory metrics collection logic to parse `vm_stat` output in a single pass using `awk`, instead of spawning multiple `grep`, `awk`, and `sed` processes for each variable. This reduces the number of subprocesses created from ~15 to ~3, improving efficiency and execution speed. 💡 What: Replaced multiple `grep | awk | sed` pipelines with a single `awk` block. 🎯 Why: To reduce process spawning overhead and improve script performance. 📊 Impact: Reduces subprocess creation by ~80% for this function. 🔬 Measurement: Verified logic correctness using a reproduction script with mocked `vm_stat` output.

Implemented a performance optimization in
metrics/system-metrics-tracker.shby refactoring the memory metrics collection logic. The new implementation parses thevm_statoutput in a single pass usingawk, replacing the previous approach that used multiple pipelines ofgrep,awk, andsedfor each variable. This change significantly reduces the number of subprocesses spawned, improving the script's efficiency. Verified the logic with a reproduction script to ensure data integrity.PR created automatically by Jules for task 15907798133658017601 started by @simien
