    CPU and System Topology

    Server Description

    General-purpose cloud server featuring dedicated quad-core processing, 15 GB RAM, and local SSD storage for balanced, entry-level production workloads.

    General Purpose

    OVHcloud b2-15 is a general-purpose cloud server configured with 4 dedicated physical vCPUs on an Intel Haswell x86_64 processor clocked at 2.0 GHz. It features 15.0 GB of memory, 16 MB of L3 cache, and 100 GB of local SSD storage under the KVM hypervisor. Benchmark results reflect entry-tier compute capabilities, placing single-core and multi-core CPU metrics in the lower quartile, alongside weak uncached memory throughput. Conversely, cached memory bandwidth and key application metrics show balanced capacity, delivering 5.93 million Redis SET operations per second and steady database performance. The absence of hyperthreading provides predictable dedicated vCPU allocation, though instruction sets are limited to baseline AVX and AES without AVX-512. The instance delivers cost-effective resource density for light database hosting, Redis caching, microservices, and general web application infrastructure.

    Performance

    Workload Profiles

    0.33Score
    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.
