Cephalocon 2019

Ceph, with its broad adoption and its integration with various platforms, is expected to handle a diverse set of workloads well. Storage workloads in the real world come in many different flavors: caching-friendly and not, data and metadata intensive, latency-sensitive and throughput-oriented, single and multi-threaded, mmap-based, aio-based.

In this talk, Manoj Pillai will present performance results and analysis for CephFS in the Nautilus release using a broad spectrum of tests covering the above cases. The evaluation will include workloads that distributed file systems generally have trouble with, and will provide results from comparable solutions where appropriate. The goal is to establish the current state of performance of CephFS, which should be useful to users, as well as to developers working to enhance CephFS performance.
