README
HashMap performance tests from java-performance.info for [Large HashMap overview](http://java-performance.info/hashmap-overview-jdk-fastutil-goldman-sachs-hppc-koloboke-trove-january-2015/#comments).
Provided benchmarks results executed 9 May 2020.
See [benchmark result charts](https://collection-libs-comparison.develar.org/).
## Running Benchmark
The full test set takes around 7 hours to complete.
```
export JAVA_HOME=~/Downloads/jbr/Contents/Home
mvn package
java -jar benchmark/target/benchmarks.jar -bm ss -wi 40 -i 40 -f 1 -foe true -rf json \
-p mapSize=100,1K,10K,100K,1M,10M -tu ms
java -jar benchmark/target/benchmarks.jar -bm ss -wi 40 -i 40 -f 1 -foe true -rf json \
-p mapSize=2,100,1K,10K -p loadFactor=0.5,0.75 -tu ms
```
## Memory Usage Measurement
Memory usage measured using [JOL](https://openjdk.java.net/projects/code-tools/jol/).
```
export JAVA_HOME=~/Downloads/jbr/Contents/Home
mvn package
# sudo is required for JOL for ptrace_scope
# specify full path to java as under sudo different environment is used
sudo ~/Downloads/jbr/Contents/Home/bin/java -Djdk.attach.allowAttachSelf=true -Djdk.module.illegalAccess.silent=true -jar memory-benchmark/target/memory-benchmark.jar
```
