Review of U.S. Area 21

Benchmark Summary

This basic performance benchmark was conducted on the target machine using bench.sh (Teddysun edition v2026-01-31). The results are as follows:

System Environment

  • OS: Alpine Linux v3.22 (x86_64)
  • Kernel: 6.1.0-50-amd64
  • Virtualization: LXC container
  • TCP congestion control: bbr
  • Network: IPv4 online, IPv6 offline
  • Location: San Jose, United States (AS402169 Uscloud Inc)

Hardware Configuration

  • CPU: Intel Xeon Gold 6133 @ 2.50GHz, 1 core
  • Memory: 122.1 MB
  • Disk: 122.1 MB
  • Swap: 122.1 MB

Benchmark Results

  • Disk I/O: Test failed with the error Not enough space for I/O Speed test!; the disk capacity was too small to write the test file
  • Network bandwidth: Both upload and download speeds were limited to approximately 9–10 Mbps. The figures were highly consistent across nodes, indicating bandwidth throttling
  • Network latency: Approximately 9 ms to local nodes; international nodes had higher latency (192 ms to Hong Kong and 262 ms to Singapore), with average return routes
  • Domestic nodes: Speed tests to Suzhou and Ningbo failed, presumably because the nodes were unreachable

Conclusion
This machine is a minimum-spec LXC container with 1 core, 122 MB of memory, 122 MB of disk space, and a 10 Mbps bandwidth limit, offering extremely limited resources. Due to these configuration limitations, disk I/O and CPU benchmarks (Geekbench, UnixBench, etc.) could not be performed; the test only covered system information and network performance. This configuration is suitable only for extremely lightweight tasks, such as a small proxy, monitoring agent, or frp client, and is not capable of hosting a conventional website or handling high-performance computing.
