Is It Worth Speeding It Up?

A decision helper for performance optimization: calculates time savings, costs, ROI, and break-even points to determine if an optimization is worthwhile.

🔗 Live Demo

Inspired by xkcd #1205.

Quick Start

git clone https://github.com/d-led/iiwsit.git
cd iiwsit
npm install
npm run dev

Visit http://localhost:5173

Usage

Input your system's parameters:

• Request rate and duration
• Expected speed gain (%)
• Implementation and maintenance time
• Time horizon

Get a YES/NO/MAYBE recommendation based on:

• Net time benefit
• ROI calculation
• Break-even analysis
• Risk assessment

Example Results

High-traffic API (1000 req/s, 500ms, 30% gain, 80hr work) → Strong YES ✅ Low-traffic job (10 req/hr, 2min, 50% gain, 200hr work) → Strong NO ❌
