Here are ten ways to perform load testing on a website, including custom scripts and commercial tools:

1. Apache JMeter: An open-source Java application that allows you to create and run load tests for web applications, APIs, and databases.

2. Locust: A Python-based open-source load testing tool that enables you to write test scenarios using Python code.

3. Gatling: An open-source load testing tool that uses a Scala-based DSL for writing test scenarios and provides a user-friendly web interface for test execution and reporting.

4. LoadRunner: A commercial load testing tool by Micro Focus that supports various protocols and technologies, including web, mobile, and enterprise applications.

5. NeoLoad: A commercial load testing solution by Neotys that offers a user-friendly interface, real-time monitoring, and advanced analytics.

6. Siege: An open-source command-line tool for load testing web servers, which can be easily scripted and automated.

7. Artillery: A modern, powerful, and easy-to-use load testing toolkit that supports testing web applications and APIs using a YAML-based configuration file.

8. k6: An open-source load testing tool built for developers, using JavaScript for scripting and providing a command-line interface and a web-based UI.

9. Tsung: An open-source distributed load testing tool that supports various protocols, including HTTP, WebDAV, SOAP, PostgreSQL, and MySQL.

10. Custom scripts using programming languages like Python, JavaScript, or Go, along with libraries such as Python's Requests, Node.js's Axios, or Go's net/http package to create and execute load tests tailored to your specific requirements.

These tools and approaches offer different features, scripting languages, and user interfaces, allowing you to choose the most suitable option based on your load testing needs, technical expertise, and budget.
