Windows Server 2025 Runs Better on ARM

3 days ago

Windows Server 2025 on ARM64 shows faster performance in virtualization tests compared to x64, with services like Active Directory and IIS responding more quickly.
The Snapdragon X Elite ARM system delivers consistent, sustained performance with low latency, while the Intel i9 system exhibits variability due to boost/throttle behavior.
ARM64's predictable scheduling benefits Hyper-V virtualization, leading to more stable VM performance for latency-sensitive server workloads.
Performance Monitor data reveals ARM64 maintains steady CPU utilization and zero processor queue length, unlike x64 which shows spikes and fluctuations.
Microsoft does not officially support Windows Server on ARM64, despite ARM's growing adoption in cloud environments like Azure and AWS.
