      CPU and System Topology

      Server Description

      A dedicated x86_64 virtual server featuring high memory density and balanced compute performance for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r7t.4xlarge is an x86_64 memory-optimized instance featuring 16 dedicated vCPUs powered by an Intel Xeon 8369B processor at 2.7 GHz. Equipped with 128.0 GB of RAM, it offers a high memory-to-vCPU ratio of 8.0 GB per core, though it lacks local storage and GPU accelerators. Operating on the KVM hypervisor, it delivers a baseline network bandwidth of 10 Gbps. Benchmark results indicate solid mid-tier performance, with a Passmark CPU score of 21137.68 and a Redis SET throughput of 15.92 million operations per second. It also exhibits strong text generation capabilities for small language models at 265.61 tokens per second. This instance is highly suitable for memory-intensive workloads, including database operations, caching layers, and software compilation.

      Workload Profiles

      1.04Score
      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.
