Peer-to-Peer Benchmark Example

The P2P benchmark measures entry distribution time in a single system. A producer puts entries and measures the time it takes for a distribution acknowledgment from a consumer. For this example, the producer and consumer have configured their data region to require acknowledgment of data distribution. The consumer region is configured as a replica, so it automatically receives all of the producer's puts.

Running the Example

Note: The tests run with a default number of samples, operations per sample, and payload. You can change these settings to better approximate your own systems. See Benchmark Parameters

Note: To run this example, you must have terminal sessions configured for the QuickStart examples, as described in Setting Up Your Environment for Running the Examples.

In one session, start the consumer:

$ java -cp "$GEMFIRE/SampleCode/quickstart/classes:$GEMFIRE/lib/server-dependencies.jar" quickstart.BenchmarkAckConsumer

After the consumer starts, in another session, start the producer:

$ java -cp "$GEMFIRE/SampleCode/quickstart/classes:$GEMFIRE/lib/server-dependencies.jar" quickstart.BenchmarkAckProducer

Example Source Files

Program and cache configuration files:

Table 1. Cache configuration files, located in SampleCode//quickstart/xml
BenchmarkAckProducer.xml	Configures a region for a distribution benchmark.
BenchmarkAckConsumer.xml	Configures a region with replication for a distribution benchmark.

Table 2. Java program files, located in SampleCode//quickstart/quickstart
BenchmarkAckProducer.java	Takes a timestamp, puts an entry value, waits for the ACK, and compares the current timestamp with the timestamp taken before the put.
BenchmarkAckConsumer.java	Creates the cache for the example.
