Trading Sample with Scala and Akka. Including performance benchmark test described in blog: http://blog.jayway.com/2010/08/10/yet-another-akka-benchmark/ === Latest Results === * 1.0-M1 With order matching: http://goo.gl/EsUwr Without order matching: http://goo.gl/UOCd2 Comparing with previous: http://goo.gl/eaoOC === How to run benchmark from distribution === Download and unzip distribution assembly from http://github.com/patriknw/akka-sample-trading/downloads The zip contains all jar files, including necessary dependencies. In the scripts directory of the distribution there is a run_benchmark.sh script that can be used to launch tests. Argument to the script is the junit test class or classes to run. ./run_benchmark.sh org.samples.trading.akka.AkkaPerformanceTest There is also a script for running all benchmark tests. ./run_all_benchmarks.sh You need to define JAVA_HOME for JDK6, if you don't have it as default. Benchmark options can be defined with variable: export BENCH_PROPS='-DuseTxLogFile=false -Dbenchmark=true -DminClients=1 -DmaxClients=40 -DuseDummyOrderbook=false' Better accuracy (running tests longer) is achieved if you define jvm parameter: -Dbenchmark=true By default the benchmark is run without transaction logging, you can use transaction logging by defining jvm parameter: -DuseTxLogFile=true By default the benchmark is run with 1 to 40 client threads, you can define another range with jvm parameters: -DminClients=2 -DmaxClients=6 To push the message passing to the limits, the order matching logic can be turned off with jvm parameter: -DuseDummyOrderbook=true To control how long the tests are running you can define repeatFactor, default is 50 when benchmark=true: -DrepeatFactor=100 To control the length of the warmup period you can define warmupRepeatFactor, default is 100 when benchmark=true: -DwarmupRepeatFactor=200
