# Is It Worth Speeding It Up?

[![License: MPL 2.0](https://img.shields.io/badge/License-MPL_2.0-brightgreen.svg)](https://opensource.org/licenses/MPL-2.0)

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

🔗 **[Live Demo](https://d-led.github.io/iiwsit/)**

Inspired by [xkcd #1205](https://xkcd.com/1205/).

## Quick Start

```bash

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 ❌

## Development

```bash

npm run dev          # Start dev server

npm run build        # Build for production

npm test             # Run unit tests

npm run test:e2e     # Run Cypress E2E tests

npm run prettier     # Format code

```

**Tech stack:** TypeScript, Vite, Tailwind CSS, daisyUI, Vitest, Cypress
