Use another method of communicating the results than trying to echo them

[motin]

Many frameworks sets the Content-Length header based on what is actually returned in the actual controller method. When curl requests the resource, it will only save output the length of Content-Length. Any remaining output, such as statements printed/echoed after the framework has run it's course will be omitted with curl in verbose mode warning: Excess found in a non pipelined read.

This means in practice that the "outdata" results are not included in the benchmarking results for these frameworks,:

May I suggest another method of communicating the results than trying to echo them? For instance, they can be written to a file. Also, the memory, time and file results should not be required/communicated when running ab tests.
