I worked on improving the aspnet (on Windows) results and I committed aspnet-stripped (based on @pdonald's aspnet tests) and HttpListener.

As that committer, I have to ask: Why would you change your career path due to supposed 'abysmal performance' reported on a website?

Keep in mind that the 'abysmal performance' of many of the frameworks can still handle millions of requests per day. Plus, many of the 'slower' frameworks have other development benefits like ease of development, community ecosystem, static type checking, etc.

The reason I replied is because I'm considering jumping from aspnet to a 'slower' framework like django and I'm not basing my decisions solely on the results of this collaborative benchmark where I don't even know if experts have tuned the results, and where I don't know why the results are 'poor'.
