      CPU and System Topology

      Server Description

      A memory-optimized x86_64 server featuring a high RAM-to-vCPU ratio and strong memory write bandwidth for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfr7.8xlarge is an x86_64 memory-optimized server instance featuring 32 dedicated vCPUs and 256.0 GB of RAM, powered by an Intel Xeon 8369HB processor running at 3.3 GHz. It operates on the KVM hypervisor and includes advanced instruction sets like AVX-512, but lacks local storage and GPU accelerators. Network connectivity is established at a baseline of 10 Gbps. Benchmark data indicates average single-core and multi-core CPU performance, alongside average memory read speeds. However, it exhibits strong memory write bandwidth for large blocks, ranking in the top 25%. This instance offers qualitative cost efficiency for memory-heavy deployments by providing a high 8:1 RAM-to-vCPU ratio. It is suitable for memory-intensive workloads such as in-memory databases, caching layers, and data processing applications that do not require local NVMe storage.

      Workload Profiles

      1.6Score
      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.Partial coverage: missing component benchmark(s): Redis RPS (pipeline=1, SET), Redis RPS (pipeline=16, SET), PassMark Memory Mark (composite), PassMark single-thread CPU.
