# Resty Perf

A simple resty lua library to benchmark memory and throughput of a function.

```lua

local function mycode()

  local x = {}

  for i = 1, 1e3 do

    local now = ngx.now()

    now = now - 45 + i

    x[i] = now

  end

  return x

end

perf.perf_time("mycode cpu profiling", mycode)

perf.perf_mem("mycode memory profiling", mycode)

```

To run it, you can use the openresty docker image:

```bash

docker run -it --rm -v ${PWD}/test.lua:/test.lua -v ${PWD}/lib/resty/perf.lua:/lib/resty/perf.lua openresty/openresty:xenial resty /test.lua

```
