Possible disadvantages of wrk

• Limited Metrics
  wrk provides basic metrics like latency and throughput, but it lacks built-in detailed analytical tools available in other performance testing tools.
• No GUI
  It is a command-line tool without a graphical user interface, which might be a barrier for non-technical users or those who prefer visual representations.
• Scripting Complexity
  While Lua scripting adds flexibility, it can also increase complexity, especially for users who are not familiar with Lua or programming.
• Limited Protocol Support
  wrk is primarily built for HTTP benchmarking, and it does not natively support other protocols such as WebSocket or gRPC.
• No Distributed Testing
  wrk does not support distributed load testing out-of-the-box, limiting its effectiveness in simulating geographically distributed traffic.
