  • Increase throughput?
  • Reduce server latency?
  • Improve client responses?
  • Speed up your testing cycles?
  • Saturation test your servers without requiring dozens of physical test clients?
  • Allow you to add the "asynchronous" keyword to your adverts so as to stack up better against your commercial rivals?

Unless you can answer the questions above without asking your manager or mentor, you are probably the wrong person to be tackling the project.
