Allow HTTP GET response body to be discarded #725
Description
Proposal
Add an option that instructs vegeta to discard the response body instead of storing it in memory.
Background
Currently when vegeta downloads files (HTTP GET) it stores the received response body in memory (I've been load testing against a 2.5G file and if I do n requests/sec, the memory usage grows to 2.5 x nG.
I want to instrument a large distributed load test suite that doesn't consume a heavy amount of memory. The ideal solution would be to stream the received request body into /dev/null or equivalent, and not consume memory to store it.
Workarounds
I don't know of a workaround for this behaviour.
