      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high memory-to-core ratio and bundled SSD storage for memory-intensive workloads.

      Memory OptimizedStorage & Database

      UpCloud HIMEM-6xCPU-128GB is a memory-optimized KVM virtual server configured with 6 AMD EPYC 7542 vCPUs running at 2.0 GHz and 128.0 GB of RAM, yielding a high ratio of 21.33 GB of memory per core. It includes a bundled 300 GB local SSD and one public IPv4 address. Benchmark data reveals a performance profile tailored for memory-heavy tasks rather than raw compute power; while CPU stress tests rank in the lower quartiles due to shared CPU allocation, memory-centric benchmarks like small-block cached reads and Redis SET operations achieve average tier results. This server is qualitatively cost-efficient for workloads requiring large memory footprints without intensive CPU demands, such as caching systems, in-memory databases, and moderate data processing tasks.

      Workload Profiles

      0.42Score
      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.
