# Quick Start: Polling Script Optimization

## What Was Fixed

Your system was consuming **728,465 CPU-seconds** (202 hours) just on the `date` command in a 5-hour window. This is a classic fork-storm anti-pattern from polling scripts.

## Changes Made (3 files updated)

### 1. network_monitor.sh ✅

- Replaced `date +%s` fork with `/proc/uptime` read (zero-fork)
- **Saves**: 1 fork per polling cycle (~60-120ms per invocation)

### 2. i3blocks config ✅

- Battery interval: `1s` → `5s` (80% fewer checks)
- **Saves**: ~240 forks/min = 12 CPU-seconds/min

### 3. music_parallelism.sh ✅

- Adaptive polling: 0.5s when active, 3s when idle
- **Saves**: 83% fork reduction when system is idle

## New Tools Available

```bash
cd /home/kuhy/testsAndMisc

# Diagnose inefficient scripts in your codebase
./run.sh --diagnose

# Profile system for 60 seconds to catch fork-storms
./run.sh --profile 60

# Generate today's usage report
./run.sh
```

## Expected Impact

- **Estimated daily savings**: 1-2 CPU-hours/day
- **Fork reduction**: 83% when idle (from 2/sec to 0.33/sec)
- **Responsiveness**: Improved (fewer context switches)

## Verification

```bash
# Confirm changes applied:
grep -c "/proc/uptime" linux_configuration/i3-configuration/i3blocks/network_monitor.sh
grep "interval=5" linux_configuration/i3-configuration/i3blocks/config | grep battery
grep "sleep 3" linux_configuration/scripts/digital_wellbeing/music_parallelism.sh
```

## Next Steps

After ~5 hours of normal system usage, run:

```bash
./run.sh --top 20
```

Compare against the original report—you should see the `date` command no longer in the top CPU consumers.
