Open Source Benchmarking for Ceph
summary
An open source Go toolset for Ceph benchmarking that actually calls C libraries to avoid Java JNI overhead, supports Librados, RBD, CephFS and RGW, and runs as sidebench (Go daemon+CLI) with a thread‑per‑core worker model so driver nodes don’t bottleneck scale tests. Features include bandwidth limiting, reproducible slice data, read/write mixes, optional deletes, and benchmaster to sweep object sizes and push results to Google Sheets; demo runs complete and produce per‑worker stats comparable to fio.
