Embarrassingly bad ApacheBench wrapper that tests from 1-16 concurrency and scrapes the most important data

test.sh

echo "warming $server ..."
ab -q -k -n 16000 -c 8 "$1" &> /dev/null
sleep 2

echo "starting test"
echo "threads, requests, test duration, req/sec, avg svc time, p50 lat, p90 lat, p99 lat, max lat"
for i in `seq 1 16`
do
  echo -n "$i "
  let j=i\*3000
  echo -n "$j "
