CPU and System Topology
Server Description
An x86_64 memory-optimized virtual server featuring sixty-four gigabytes of RAM and eight dedicated vCPUs for memory-intensive, low-compute workloads.
Alibaba Cloud ecs.u0.c1m8.2xlarge is an x86_64 memory-optimized server instance featuring 8 dedicated vCPUs and 64.0 GB of RAM. Powered by an Intel Xeon 8163 processor running at 2.5 GHz, this KVM-based instance provides 8.0 GB of memory per core but lacks local storage and GPU acceleration. Performance benchmarks indicate modest CPU capabilities, with stress-ng and Geekbench scores generally falling into the bottom 25% tier. However, the instance maintains average performance in large-block memory write bandwidth and small-scale LLM inference. With a baseline network bandwidth of 2 Gbps, this configuration is qualitatively cost-efficient for memory-heavy, compute-light workloads. It is best suited for caching, lightweight database tasks, and basic text processing rather than CPU-intensive compilation or high-throughput web serving.
