To understand the performance characteristics of APEX File Storage for AWS, a standard benchmark tool was used for sequential read and sequential write tests with NFS version 3. Sequential read workloads with a request size of 128 KiB and sequential write workloads with a request size of 512 KiB were tested.
Regarding the sequential read/write tests, here are a few specifics:
The OneFS inline compression and inline deduplication features were left at their defaults (enabled) during all tests.
In the tests, we used 12 c5.18xlarge clients to generate I/O to the OneFS clusters. Each client instance contained 72 vCPU cores and 144 GiB memory, and the network bandwidth was 25 Gbps. For each test, we followed the rule of ensuring that the aggregated EBS bandwidth exceeded the instance-level EBS bandwidth.
All performance tests in this document were performed in the US East (N. Virginia) Region (us-east-1), in the same Availability Zone.
