CPU and System Topology
Server Description
A shared-CPU virtual server offering balanced multi-core performance and moderate memory capacity for non-intensive multi-threaded workloads.
Alibaba Cloud ecs.n4.4xlarge is an x86_64 server instance utilizing a shared Intel Xeon 8163 processor with 16 vCPUs, 8 physical cores, and 32.0 GB of system memory. Operating on the KVM hypervisor, this instance does not include local storage or GPU accelerators, and features a baseline network bandwidth of 2 Gbps. Benchmark data reveals weak single-core performance, with single-threaded compression and Geekbench scores in the bottom decile. Conversely, multi-core performance, static web serving, and database operations achieve average tier results. This resource profile makes the instance a qualitatively cost-effective option for multi-threaded workloads, software compilation, and static web hosting where shared CPU allocation is acceptable, while remaining less suitable for memory-heavy or single-thread-bound applications.
