S3 Benchmark Harness

This module contains performance tests for S3AsyncClient and S3TransferManager

How to run

# Build the JAR
mvn clean install -pl :s3-benchmarks -P quick --am

# download
java -jar s3-benchmarks.jar --bucket=bucket --key=key -file=/path/to/destionfile/ --operation=download --partSizeInMB=20 --maxThroughput=100.0

# upload
java -jar s3-benchmarks.jar --bucket=bucket --key=key -file=/path/to/sourcefile/ --operation=upload --partSizeInMB=20 --maxThroughput=100.0

How to run S3Express (temporary)

This benchmark is currently separate. Until it's integrated with the other benchmark runner, the usage is as follows:

mvn exec:exec -Dexec.executable="java" -Dexec.args="-cp %classpath software.amazon.awssdk.s3benchmarks.s3express.S3BenchmarkRunner"

Command line arguments

Benchmark version

The --version command line option is used to determine which component is under test:

• --version=crt : Indicate to run the benchmark for the CRT's S3Client
• --version=java : Indicate to run the benchmark for the java based S3 Async Client (MultipartS3AsyncClient class)
• --version=v2: SDK v2 transfer manager (using S3CrtAsyncClient to delegate requests)
• --version=v1: SDK v1 transfer manager (using AmazonS3Client to delegate requests)

Operation

The --operation command line argument determine which transfer operation is used

operation	supported version
download	v1 v2 java crt
upload	v1 v2 java crt
download_directory	v1 v2
upload_directory	v1 v2
copy	v1 v2 java

All command line argument can be found in the BenchmarkRunner class.

Benchmark scripts Automation

From the .script folder, use one of the benchamrk scripts to run a test suite.

single file benchmark

usage

benchmark download|upload fs|tmpfs|no-op [<size>]

The scripts require the operation (download or upload) and the location of the type of file system.

• operation: download|upload
• file system: fs|tmpfs
  • fs: regular file system, under the root (/) directory
  • tmpfs: in-memory file system (under the /dev/shm directory)
• size (opt): if specified, will only run the test with the specified size (file must exist)

The Benchmark suite will run the specified operation with different file sizes (1b 8MB+1 8MB-1 128MB 4GB 30GB, if no size are specified) and with the different client (v1 TM, v2 TM and CRT S3 client) and save the result for each benchmark under result/$operation_$location_$name_$version_$size".txt ie: result/download_tmpfs_TMv2_128MB.txt. For upload benchjmarks, the files 1b 8MB+1 8MB-1 128MB 4GB 30GB must all exists under / for fs or /dev/shm/ for tmpfs. The create_benchmak_file script can be used to create them.

copy benchmark

benchmark-copy [<size>]

Files 1b 8MB+1 8MB-1 128MB 4GB 30GB, or the one passed as an argument, need to exist in the s3 bucket.

directory benchmark

benchmark-dir download|upload fs|tmpfs [1B|4K|16M|5G]

• fs is located ia ~/tm_dire_file
• tmpfs is located at /dev/shm/tm_dir_file

Graph scripts

The ploy.py creates Box and Whiskers type bar graphs of the test data. The data is hard coped in the script file.

dependencies: plotly

pip install plotly

creating static images also requires Kaleido (more info)

pip install kaleido

then simply run the plot.py script to generate images in ../images (will be created if it does not exist)

python plot.py
