Running Performance Tests
-------------------------
This performance test suite contains a number of tests.
- Service request-reply
- Ping-Pong
- Topic
Service request-reply
---------------------
Description:
This is the simplest test to ensure everything is working. This involves
one client that is known as a "service provider" and it listens on a
well-known queue for requests. Another client, known as the "service requester"
creates a private (temporary) response queue, creates a message with the
private response queue set as the "reply to" field and then publishes the
message to the well known service queue. The test allows you to time how long
it takes to send messages and receive the response back. It also allows varying
of the message size.
Quick Run:
./serviceRequestReply-QuickTest.sh <brokerdetails> <number of messages>
This provides a quick test to run everything against a running broker. Simply specify broker and number of messages to run.
Detailed Run:
You must start the service provider first:
serviceProvidingClient.sh <brokerdetails> [<P[ersistent]|N[onPersistent]> <T[ransacted]|N[onTransacted]>] [selector]
where Brokerdetails is the connection information to the broker you are running on; e.g. localhost or localhost:5670 or tcp://10.10.10.10:5677.
By default Non Persistent, Non Transaction messages are used in the response. A selector may also be specified.
To run the service requester:
serviceRequestingClient.sh <Brokerdetails> <Number of Messages> [<Message Size>] [<P[ersistent]|N[onPersistent]> <T[ransacted]|N[onTransacted]>]
This requests the <number of messages> of a <Message Size (default 4096 bytes>. By default the connection is Non Persistent and Non Transactional.
After receiving all the messages the client outputs the rate it achieved.
Ping-Pong

Topic
-------
Description:
A more realistic test is the topic test, which tests the
performance of the topic exchange to a configurable number of clients (e.g. 50).
A publisher sends batches of of messages to a topic that a number of clients are
subscribed to. The clients recevie each all the messages and then send a response.
The time taken to send all messages and receive a response from all clients is displayed.
Quick Run:
./topic-QuickTest.sh <host> <port> <messages> <clients> <batches>
This provides a quick test to run everything against a running broker. Simply specify host, port, the number of messages, number of clients and number of batches to run this quick test.
Detailed Run:
You must run the listener processes first:
run_many.sh 10 topic "topicListener.sh [-host <host> -port <port>]"
In this command, the first argument means start 10 processes, the
second is just a name use in the log files generated and the third
argument is the command to run the specified number of times.
The topicListener by default connects to localhost:5672 this can be changed using the above flags.
Then run the publisher process:
headersPublisher.sh [-host <host> -port <port> -messages <number> -clients <number> -batch <number>]
The default is to connect to localhost:5672 and send 1 batch of 1000 messages expecting 1 client to respond.
Note that before starting the publisher you should wait about 30
seconds to ensure all the clients are registered with the broker (you
can see this from the broker output). Otherwise the numbers will be
slightly skewed.
Additional parameters to scripts
Publisher
-payload <int> : specify the payload size (256b Default)
-delay <long> : Number of seconds to send between batches (0 Default)
-warmup <int> : Number of messages to send as a warm up (0 Default)
-ack <int> : Acknowledgement mode
- 1 : Auto
- 2 : Client
- 3 : Dups_OK
- 257 : No (Default)
- 258 : Pre
-factory <string> : ConnectionFactoryInitialiser class
-persistent <"true"|other> : User persistent messages if string equals "true" (false Default)
-clientId <string> : Set client id
-subscriptionId <string> : set subscription id
