Drab is slow in production

It may make sense that the latency of the network increase time from one to five seconds.

@wlminimal, can you measure how long this single poke takes in dev and prod? Just measure the time difference:

IO.puts(" ++++++++++++ poking +++++++++++++")
t0 = :os.system_time(:milli_seconds)
poke(socket,
  total_sent: total_sent,
  deilvered_count: deilvered_count,
  undelivered_count: undelivered_count,
  total_clicks: total_clicks
)
IO.puts("+++++++++++++ poking is done ++++++++++")
IO.puts("it took #{:os.system_time(:milli_seconds) - t0} ms")
