CPU and System Topology
Server Description
A dedicated compute-optimized instance featuring eight vCPUs and a balanced memory profile for moderate application workloads.
Alibaba Cloud ecs.c5.2xlarge is a compute-optimized instance featuring 8 dedicated vCPUs from an Intel Xeon 8163 processor running at 2.5 GHz, paired with 16.0 GB of RAM. Built on the KVM hypervisor, this x86_64 architecture instance does not include local storage or GPUs, and it operates with a baseline network bandwidth of 2 Gbps. Benchmark results show weak performance in single-core and multi-core stress-ng tests, Geekbench suites, and database operations, though it maintains average performance in Passmark CPU tests and large-block uncached memory bandwidth. The instance is best suited for workloads with moderate resource demands, such as lightweight web serving, small-scale batch processing, and basic application hosting where dedicated CPU allocation is required but memory and storage needs remain low.
