This tool offers the ability to run very basic throughput benchmarking against an S3-compatible endpoint. It does a series of put operations followed by a series of get operations and displays the corresponding statistics. The tool uses the AWS Go SDK.
- Go
Build for regular amd64 arches (linux):
GOOS=linux GOARCH=amd64 go build -o s3bench .Run the following command to build the binary.
go get github.com/igneous-systems/s3bench
The binary will be placed under $GOPATH/bin/s3bench.
The s3bench command is self-describing. In order to see all the available options just run s3bench -help.
The following will run a benchmark from 2 concurrent clients, which in aggregate will put a total of 10 unique new objects. Each object will be exactly 1024 bytes. The objects will be placed in a bucket named loadgen. The S3 endpoint will be ran against http://endpoint1:80 and http://endpoint2:80. Object name will be prefixed with loadgen.
./s3bench -accessKey=KEY -accessSecret=SECRET -bucket=loadgen -endpoint=http://endpoint1:80,http://endpoint2:80 -numClients=2 -numSamples=10 -objectNamePrefix=loadgen -objectSize=1024 -csvOutput
By default, the region used will be igneous-test , a fictitious region which
is suitable for using with the Igneous Data Service. However, you can elect to
use this tool with Amazon S3, in which case you will need to specify the proper region.
It is also important when using Amazon S3 that you specify the proper endpoint, which
will generally be http://s3-regionName.amazonaws.com:80. EG: if the bucket which you are
testing is in Oregon, you would specify:
-endpoint http://s3-us-west-2.amazonaws.com:80 -region us-west-2
For more information on this, please refer to AmazonS3 documentation.
The output will consist of details for every request being made as well as the current average throughput. At the end of the run summaries of the put and get operations will be displayed.
