To test Object Storage performance, use Warp. Warp is an open-source benchmarking utility designed to check performance of S3-compatible storage. It measures throughput and delivers reproducible, comparable results across any S3 environment.

​
Prerequisites

  1. Install Warp: 
    wget https://dl.min.io/aistor/warp/release/linux-amd64/warp
chmod +x warp
  2. Create an Object Storage bucket if you don’t have one.
  3. Create an access key. You need its AWS-like ID and secret key to run benchmark tests. When you create the access key by using the CLI, the AWS-like ID and secret key are specified in the .status.aws_access_key_id and .status.secret parameters of the output.

How to run benchmark tests

The example below showcases how to check the maximum single-node performance for read and write operations. Warp provides multiple tests for S3 methods. If you want to test a different use case, see the Warp repository for documentation or contact technical support. To run benchmark tests:
  1. Prepare environment variables for the tests: 
    export S3_ENDPOINT="storage.<region>.nebius.cloud:443"
export S3_BUCKET="<bucket_name>"
export S3_ACCESS_KEY="<AWS-like_ID>"
export S3_SECRET_KEY="<secret_key>"
    In the S3_ENDPOINT variable, specify the same region where your bucket is located.
  2. Test the read performance: 
    ./warp get \
   --host "$S3_ENDPOINT" \
   --tls \
   --bucket "$S3_BUCKET" \
   --access-key "$S3_ACCESS_KEY" \
   --secret-key "$S3_SECRET_KEY" \
   --objects 5000 \
   --obj.size 10MiB \
   --duration 5m \
   --storage-class STANDARD \
   --concurrent 128
    Adjust the following parameters to your workload profile:
    • --objects: Number of objects to upload. The default value is 2500 but for better test results, specify at least 5000.
    • --obj.size: Size of each generated object. Specify the value as nKiB, nMiB or nGiB, for example, 100KiB. The default value is 10MiB.
    • --duration (optional): Duration of the test. Specify the value as Nm, for example, 7m. The default value is 5 minutes. Run the test for at least 5–10 minutes to see how stable the performance is.
    • --storage-class (optional): Storage class to use. Set STANDARD or ENHANCED_THROUGHPUT. If not specified, the default storage class of the bucket is applied.
    • --concurrent: Runs multiple concurrent operations per Warp client and sets the number of these operations. The default value is 20. Adjust the value, considering the following recommendations:
      • The value range should be within 32–200.
      • For small objects, run the test with a higher concurrency. For large objects, run it with a lower concurrency.
      Try changing the number to find an optimal value. It depends on a selected storage class and on the machine where you run the test (for example, Compute virtual machine, your local machine or the internet).
  3. Test the write performance: 
    ./warp put \
  --host "$S3_ENDPOINT" \
  --tls \
  --bucket "$S3_BUCKET" \
  --access-key "$S3_ACCESS_KEY" \
  --secret-key "$S3_SECRET_KEY" \
  --obj.size 10MiB \
  --concurrent 128
    Adjust the --obj.size and --concurrent parameters in the same way as in the read performance test.
