Since I will forget this:
ab -c 10 -n 100 http://127.0.0.1:3000/observations/1602.json
ab is a simple benchmarking tool from Apache.
-c 10 means 10 concurrent connections,
-n 100 means 100 requests. Note that it gave me
Benchmarking localhost (be patient)...apr_socket_recv: Connection refused (61) when I tried it on
http://localhost:3000/, but that seems to be an IPv6 thing and replacing that with
127.0.0.1 seemed to work.
You can also do this with POST requests if you have HTTP Basic auth:
echo "observation[latitude]=38&observation[longitude]=-121" > post.txt && \ ab -c 10 -n 100 \ -A username:password \ -T application/x-www-form-urlencoded \ -p post.txt \ "http://127.0.0.1:3000/observations" && \ rm post.txt
Haven’t found a way to just give it POST params without creating a file, but whatever, this works.
