      Server Description

      A dedicated compute-optimized virtual server featuring Intel Xeon processors, tailored for CPU-intensive workloads requiring no local storage.

      Compute Optimized

      Amazon Web Services c4.2xlarge is a compute-optimized virtual server featuring 8 vCPUs and 15.0 GB of memory, running on an Intel Xeon E5-2666 v3 processor at 2.9 GHz. Utilizing the Xen hypervisor and x86_64 architecture, this instance allocates dedicated CPU resources but does not include local storage or GPU accelerators. It offers a baseline network bandwidth of 2 Gbps. Performance benchmarks generally fall into the average tier, with a Geekbench multi-core score of 4493.0 and a static web serving throughput of 6.85 GB/sec. However, it exhibits weaker performance in multi-threaded decompression and Redis operations, and poor throughput for medium-sized LLM inference. Qualitatively, the c4.2xlarge provides a cost-effective option for compute-heavy tasks that do not require local NVMe storage. It is best suited for workloads such as software compilation, static web serving, image processing, and moderate CPU-based simulations.

      Workload Profiles

      0.38Score
      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.
