Kitura-based JSON serialization performance testcase. A number of routes are provided for testing the performance of serializing Int, UInt, Double and Float number types with either a default value, or one that you provide. There are also routes for Bool and purely String types.
The serialized payload is configurable via the following environment variables, which should be set prior to launching the application:
TESTVALUE: sets the number to be serialized. (default 1234)TESTCOUNT: sets the number of elements in the dictionary being serialized. (default 10)
- Build the project
git clone https://github.com/djones6/jsonPerf ~/jsonPerf
cd ~/jsonPerf
swiftenv local <baseline swift build>
swift build -c release --build-path=baselineBuild
swiftenv local <new swift build>
swift build -c release --build-path=newBuild
- Get the driver scripts and prereqs
git clone https://github.com/djones6/Kitura-Bench ~/kiturabench
For Linux, you need these packages:
sudo apt-get install numactl sysstat
- Get the 'wrk' tool (my fork, 'interval' branch adds the -i option to provide periodic throughput measurements)
git clone https://github.com/djones6/wrk.git -b interval
cd wrk
make
This will build wrk, then you need to put it on your path:
export PATH=$PATH:$HOME/wrk
(you could add this to your .bashrc)
- Run a compare:
env TESTVALUE=123456 TESTCOUNT=20 URL=http://localhost:8080/jsonInt ITERATIONS=5 DURATION=60 ~/kiturabench/compare.sh ~/jsonPerf/baselineBuild/release/JSON ~/jsonPerf/newBuild/release/JSON
If you want to test your builds first, just launch the binary you built and then point your browser to eg: http://localhost:8080/jsonInt
You can launch it manually like this:
env TESTVALUE=123456 TESTCOUNT=20 newBuild/release/JSON
