kioperf

Golang utility to measure I/O performance on block storage and object storage

Building

make

Testing performance of block storage

Test performance of writing 10 25MiB files using three threads. Iterations should be equal to files (or greater). Files will be written to ./kioperf-data directory (default).

mkdir test
./kioperf disk --operation=write --size 25 --threads=3 --iterations=10 --files=10

Test performance of reading from a collection of 10 files 100 times in total.

./kioperf disk --operation=read --threads=3 --iterations=100 --files=10

Testing performance of object storage.

Test performance of writing 10 25MiB files to object storage using three threads. Files will be written to s3://my-own-us-west-2-playground-1/kioperf/.

export AWS_ACCESS_KEY_ID="access key string"
export AWS_SECRET_ACCESS_KEY="secret key string"
./kioperf s3 --operation=write --bucket=my-own-us-west-2-playground-1 \
 --prefix=kioperf/ --size 25 --threads=3 --iterations=10 --files=10

Test performance of reading from the same files 100 times.

./kioperf s3 --operation=write --bucket=my-own-us-west-2-playground-1 \
 --prefix=kioperf/ --threads=3 --iterations=100 --files=10
