CPU and System Topology
Server Description
A dedicated x86_64 compute platform with balanced memory allocation and 10 Gbps networking for stable general-purpose workloads.
Alibaba Cloud ecs.cm4.6xlarge is a general-purpose instance featuring a dedicated Intel Xeon 8369HB processor with 24 vCPUs, 12 physical cores, and 96.0 GB of RAM. Operating on the x86_64 architecture under the KVM hypervisor, it delivers a balanced 4.0 GB of memory per core but lacks local storage and GPU accelerators, utilizing a 10 Gbps baseline network interface. Benchmark results indicate steady mid-range performance, with a stress-ng multi-core score of 24949.83 and a PassMark database score of 6820.79. The instance supports AVX-512 extensions, facilitating multi-threaded decompression at 109.04 GB/sec and static web serving at 14.7 GB/sec. Given its dedicated CPU allocation and balanced resource profile, it is suited for software compilation, static web serving, Redis databases, and lightweight machine learning inference.
