What elbencho is
elbencho is a free, distributed storage benchmark for measuring latency, throughput, and IOPS across file systems, object stores, and block devices, including GPU storage. It can test local or shared storage using distributed service mode and provides live statistics while systems are under load. GPU data-transfer tests can use Nvidia CUDA or GPUDirect Storage. Results can be exported as CSV or JSON, and an integrity verification option is available. Optional S3 support is based on the AWS SDK for C++; source builds need S3_SUPPORT=1 to enable it. NVMe-oF initiator support can be enabled with SPDK. The README includes examples for Slurm and Kubernetes, and macOS build instructions using Homebrew. Downloads include Linux packages and static executables for amd64/x86_64 and arm64/aarch64, plus a Windows build with required DLLs. The static Linux executable does not include GPU support; the release page recommends a source build or GPU-enabled container for that capability. elbencho is licensed under GPL-3.0.
Good
- Measures latency, throughput, and IOPS.
- Supports distributed testing on local and shared storage.
- Live statistics show system behavior under load.
- Offers data integrity verification.
- CSV results can be used for charts.
Watch out
- Static Linux executables do not include GPU support.
- S3 support is not enabled by default in source builds.
- GPU tests require CUDA or GPUDirect Storage.
Who it suits
elbencho suits users comparing storage performance across one or multiple clients, including GPU data-transfer tests for deep-learning workloads. It is aimed at people comfortable with storage benchmarking and platform-specific builds.
Verdict
elbencho covers several storage types and distributed workloads, with live statistics and integrity checks. Choose the appropriate build if GPU testing or optional integrations are required.
