      CPU and System Topology

      Server Description

      A memory-optimized x86 virtual server featuring 16 vCPUs, 128 GB RAM, and AVX-512 support for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.se1.4xlarge is a memory-optimized instance featuring 16 dedicated vCPUs from an 8-core Intel Xeon 8269CY processor operating at 2.5 GHz, supported by 128.0 GB of RAM. The instance includes 35 MB of L3 cache, instruction support for AVX-512 and AES, and operates under KVM virtualization with a 3 Gbps baseline network bandwidth. It lacks local disk storage and dedicated GPU acceleration. Benchmark data demonstrates a key trade-off: single-core CPU execution ranks in lower performance tiers due to moderate clock frequencies, whereas multi-core throughput, software compilation, and memory bandwidth achieve average mid-range scores. With an 8 GB per vCPU allocation ratio, this server provides qualitative cost efficiency for memory-heavy workloads, making it well-suited for large-scale key-value stores like Redis, in-memory databases, and web serving applications relying on network storage.

      Workload Profiles

      0.56Score
      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.
