Benchmark results in GCP VM

Setup

Results in Google Cloud (GCP) VM using JDK 17. Running on n1-standard-32 VM (32 CPUs, 120GB RAM), CentOS 7.

In the OffHeapGetPutBenchmark test NMA and RocksDB are populated with 50,000 byte array values of size 100KB each (5GB of data)

The keys are the strings "0" - "49999"

In NMA tests data is not persisted on disk.

Command to build JMH fat-jar:

./gradlew clean jmhJar

JMH Configuration:

# JMH version: 1.35
# VM version: JDK 17.0.6, Java HotSpot(TM) 64-Bit Server VM, 17.0.6+9-LTS-190
# VM invoker: /home/bastion/jdk-17.0.6/bin/java
# VM options: -Xmx4G -Drocksdb.dir=/tmp/tmpfs/rocksdb
# Blackhole mode: compiler (auto-detected, use -Djmh.blackhole.autoDetect=false to disable)
# Warmup: 10 iterations, 10 s each
# Measurement: 20 iterations, 10 s each
# Timeout: 10 min per iteration
# Threads: 32 threads, will synchronize iterations
# Benchmark mode: Throughput, ops/time

For rocksdb create a 10GB tmpfs mount:

mkdir /tmp/tmpfs
mount -t tmpfs -o size=10G tmpfs /tmp/tmpfs/

Results

Run Command:

 ./gradlew clean jmh
