simple wrk benchmark for posting binary file

postFile.lua

--Read the binary file, lua takes binary files with no difference to strings(all UNIX;https://www.lua.org/pil/21.2.2.html). But, use 'b' tag
local inp = assert(io.open("xxxx.xml.gz", "rb"))

local data = inp:read("*all")

--HTTP custom settings
--Remember to set the schema, host and port here otherwise it will use default.
wrk.scheme = "http"
wrk.host = "localhost"
wrk.port = 3000
wrk.method = "POST"
wrk.path = "/"
wrk.headers["Content-Encoding"] = "gzip"
wrk.headers["Content-Type"] = "text/xml"

wrk.body = data
