    CPU and System Topology

    Server Description

    A dedicated AMD EPYC instance featuring high memory density and NVMe storage for demanding database and caching workloads.

    Memory OptimizedStorage & Database

    OVHcloud r3-256 is a memory-optimized server instance configured with 32 dedicated AMD EPYC physical cores and 32 vCPUs running at 2.3 GHz without hyperthreading. It features 256.0 GB of RAM, providing a high ratio of 8.0 GB per core, alongside a 400 GB NVMe SSD and an 8 Gbps baseline network bandwidth. Benchmark results place this instance in the top 25% for multi-core CPU performance, memory bandwidth, and database operations, with Redis SET performance reaching 75.95 million operations per second. Single-core performance and web serving throughput remain in the average tier. The dedicated core allocation and high memory density deliver strong qualitative cost efficiency for memory-heavy workloads. This server is well-suited for hosting large-scale databases, in-memory caching systems, software compilation, and medium-scale machine learning inference tasks.

    Workload Profiles

    2.15Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
