avalanche

Perform stress load test on specific URL in avalanche-fetching manner

Motivation

• Explore server boundaries with maximum requests
  • trigger errors like Error: ENFILE: file table overflow
  • memory usage
• Measure response per second (rps) of specific URL
• Testing recoverability after denial of service simulation

Example

$ make build
$ ./avalanche https://localhost:3001/users
