      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated Intel Xeon processors and high memory density for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r7t.8xlarge is a memory-optimized virtual machine instance featuring 32 dedicated vCPUs and 256.0 GB of RAM, running on an Intel Xeon 8369B processor at 2.7 GHz. Built on the x86_64 architecture with the KVM hypervisor, this instance provides a high memory-to-core ratio of 8.0 GB per core, though it lacks local storage and GPU accelerators. Performance benchmarks indicate average tier results across most metrics, including a PassMark CPU score of 36647.59 and a Redis SET throughput of 31.33 million operations per second. It exhibits strong performance in text generation for small language models, reaching 312.77 tokens per second. Lacking local storage, it relies on a 16 Gbps baseline network bandwidth. This profile makes the instance suitable for memory-intensive workloads such as database operations, caching layers, and static web serving.

      Workload Profiles

      1.8Score
      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.
