GettingStarted

A guide to checking out the code, building it and running the performance tests
Phase-Deploy

Updated Sep 11, 2011 by mjpt...@gmail.com

Getting Started

1. Check out the project locally to your machine

    > cd ${MY_PROJECTS_HOME}
    > svn checkout http://disruptor.googlecode.com/svn/trunk/ disruptor-read-only

2. Build a distribution

    > cd ${MY_PROJECTS_HOME}/disruptor-read-only/code
    > ant

As a result of the build you should find the following files:

    ${MY_PROJECTS_HOME}/disruptor-read-only/code/target/dist/disruptor.jar
    ${MY_PROJECTS_HOME}/disruptor-read-only/code/target/dist/disruptor-api.jar
    ${MY_PROJECTS_HOME}/disruptor-read-only/code/target/dist/disruptor-src.jar

3. Run the performance tests

    > cd ${MY_PROJECTS_HOME}/disruptor-read-only/code
    > ant throughput:test
    > ant latency:test

Hi All-

First off, the Disruptor is really pretty sharp. I must say I am extremely impressed by the throughput and latency performance you all have achieved with this.

I do have a slight problem, however when I run the throughput:test target from the ant build. Every time the com.lmax.disruptor.ThreePublisherToOneProcessorSequencedThroughputTest? is run it seems as if it just sits there. Does this particular perf. test take an exceptionally long time to run? My machine specs are as follows:

MacBook? Pro 2,1 4GB of RAM 256 SSD Core 2 Duo @ 2GHz

My java version is as follows:

java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425) Java HotSpot?(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)

Would this configuration be causing any problems? Any advice and/or help would be greatly appreciated. Again, great work and thanks for your time!

Cheers,

Thomas

Hi All-

I figured out the problem and it turns out it's because my processor is just... slow :(. Anyway, I kicked down the number of ITERATIONS to 30MM from 300MM it finished in somewhat of a reasonable amount of time. Just thought I'd pass this along if anyone else runs the perf. tests on a machine with comparable specs to my own.

Cheers,

Thomas

Hello,

First I would like to say that I am a big fan of Disruptor, as it allowd me to learn a lot of cool stuff.

My discovery: I have checked out and build latest version of the disruptor – 2.8. and build it.

When I run: ant latency:test I receive follwing failure: junit.framework.AssertionFailedError?: at com.lmax.disruptor.ThrottledOnePublisherToThreeProcessorPipelineLatencyTest?.shouldCompareDisruptorVsQueues(ThrottledOnePublisherToThreeProcessorPipelineLatencyTest?.java:216)

My configuration:

Toshiba Tecra S11 with 8GB RAM

Windows 7 Professional 64Bit Servis Pack 1

java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot?(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)

throughput:test Passes everything ok.

Cheers,

Dusan
