This Gem has two parts, slow_server and slow_client, together they can be used to test timeouts in various stages of connections.
Currently there are two types of delays supported by both client and server, initial delay and chunk delay.
Initial delay (--delay) causes both client and server to wait some amount of seconds after the connection is opened before sending anything.
Chunk delay (--chunk-delay) works together with chunk count (--chunks) to split the message into chunks and send them one chunk at a time with some delay between. You can think of this similar to Chunked Encoding for HTTP, but it's not actually using Chunked Encoding
$ gem install slow_server
###slow_client
slow_client is somewhat similar to slowloris, it has tunable delays for various different phases of connection.
$ slow_client --help
Usage: slow_client [OPTIONS] [URI]
-X, --method METHOD Request Method (default: GET)
-p, --port NUMBER Listen Port (default: 4000)
-c, --chunks BYTES Chunks (default: 1)
-d, --delay SECONDS Transmission delay after connecting (default: 0)
-k, --chunk-delay SECONDS Delay between chunks (default: 0)
-v, --version Show Version
###slow_server
slow_server is the counterpart to slow_client, by default it will respond with the story of The Tortoise and The Hare, but it too has tunable delays.
$ slow_server --help
Usage: slow_server [OPTIONS] [RESPONSE]
-p, --port NUMBER Listen Port (default: 4000)
-c, --chunks BYTES Chunks (default: 1)
-d, --delay SECONDS Transmission delay after connecting (default: 0)
-k, --chunk-delay SECONDS Delay between chunks (default: 0)
-v, --version Show Version
