s4

S3 Stress (S4) and Benchmark Swiss Army Knife

Usage

  • Clone this repository or just download bin/linux/s4 and configuration files from configs
  • Create a Bucket on S3
  • Store S3 credentials in ~/.aws/credentials. For more info see: https://docs.aws.amazon.com/cli/latest/userguide/cli-config-files.html
  • Edit or create a yaml configuration file (see configs for examples)
  • Before you can test GET ops, first PUT enough data to S3 by running s4 -c <yaml configuration for writes>. Example 100% PUT test:
ubuntu@golang-dev:~$ ./s4 -c configs/writes.yaml
--- config:
{http://s3-region.example.com false s4_test 0 false [{job1 1Mib 75 100} {job2 4Mib 75 100}] []}

  • After all threads * iterations have finished or ctrl-c is pressed, the total result is reported:
2018/05/21 13:04:34 Elapsed time in seconds: 20.920798
2018/05/21 13:04:34 Total OPS: 6536, operations per second: 326, bytes per second: 912 MiB
  • Now do a read benchmark, or simulate a mixed workload

Optionally use -l during a write or mixed workload to log all Object names and md5 hashes.

Configuration

Configuration is very simple. Example:

# s4 configuration
s3_endpoint: http://s3-region.example.com
bucket: s4_test
read_range_max: 100
# read_sparse: false
# tls_no_verify: false
# random_data: false

read:
  - name: job1
    recordsize: 1mib
    threadcount: 10
    iterations: 100
  - name: job2
    recordsize: 4mib
    threadcount: 10
    iterations: 100

write:
  - name: job1
    recordsize: 1mib
    threadcount: 10
    iterations: 100
  - name: job2
    recordsize: 4mib
    threadcount: 10
    iterations: 100

The above would be a mixed read/write test with 2 jobs for both reads as writes with 1mib and 4mib Object sizes each

Options

s3_endpoint

The S3 endpoint to test against

bucket

The name of the Bucket in S3. Create the Bucket before testing

read_range_max

When testing reads, test against range read_range_max Objects. Eg. when set to 100 s4 will (re-)read from the 1st 100 Objects

read_sparse

With reads, when set to true s4 reads response ContentLength and does not wait to stream the full payload. Defaults to false

tls_no_verify

When using HTTPS and set to true, this disables certificate verification. Defaults to false

random_data

When set to true S4 generates psuedo-random data
