All Plan Configurations Overview

For easier comparison, here is a table summarizing all plans in this series:

Hardware Performance Review

We used professional testing scripts to evaluate this VPS’s hardware performance. (Data Source: NodeQuality Full Report)

1. System Basic Information

Processor  : AMD EPYC 7452 32-Core Processor
CPU cores  : 2 @ 2345.592 MHz
RAM        : 1.9 GiB
Swap       : 1024.0 MiB
Disk       : 26.2 GiB
Distro     : Debian GNU/Linux 12 (bookworm)
Kernel     : 5.15.0-144-generic

The system information shows this VPS is equipped with a powerful AMD EPYC 7452 processor running at ~2.35GHz.

2. CPU Performance Benchmarks

Using Geekbench 5 and SysBench, the results are:

• Geekbench 5:
  • Single-core score: 1042
  • Multi-core score: 2022
  • Full Report
• SysBench CPU:
  • Single-threaded score: 1644
  • Dual-threaded score: 3281

Summary: The EPYC 7452 CPU performs exceptionally well. Both single-core and multi-core benchmarks are high, sufficient for most compute-intensive tasks.

3. Disk I/O Performance

Using fio to test disk read/write speeds, results show the NVMe SSD performs impressively:

Summary: Disk I/O is a major highlight. Read/write speeds easily surpass 1GB/s, ensuring fast response for websites and databases.

4. Memory Performance

• SysBench Memory Test:
  • Single-threaded read: 44,226.85 MB/s
  • Single-threaded write: 19,817.60 MB/s

Summary: Memory read/write speeds are very fast. Combined with a high-performance CPU, data processing is highly efficient.

Network Performance Review

Network quality is the core metric for a mainland-optimized VPS.

1. Network Latency (Ping)

Ping tests from various nodes in mainland China show excellent latency:

• National average latency: 64ms
• China Telecom average: 62ms
• China Unicom average: 57ms
• China Mobile average: 74ms

For regions like East China (Shanghai), Telecom latency is as low as 32ms, and Unicom 36ms. Even distant regions like Southwest and Northwest maintain latency below 100ms.

2. Outbound Routing

• Telecom: From Sichuan Telecom → Shanghai exit → Direct connect to Japan SoftBank, high-quality route.
• Unicom: From Jiangsu Unicom → Shanghai exit → Direct connect to Japan SoftBank, excellent route quality.
• Mobile: From Guangdong Mobile → via Hong Kong CMI → Japan Lumen, optimized mainstream Mobile route.

3. Return Routing

Return routes determine download speeds from the VPS. Tests show all three networks have direct connections:

• Telecom return: AS979 -> AS4134 (China Telecom backbone), direct to mainland.
• Unicom return: AS979 -> AS10099 (China Unicom backbone), direct to mainland.
• Mobile return: AS979 -> AS58453 (CMI), direct via Hong Kong CMI to mainland.

Summary: Both outbound and return routes are fully optimized for mainland China’s three major ISPs, ensuring low latency and high stability.

4. Mainland Node Speed Tests

Observation: Telecom and Unicom nearly saturate the 300Mbps bandwidth. Mobile download speed appears abnormal, possibly due to the test node, but upload speed is normal. Additionally, using a Trojan proxy, YouTube playback on a local Mobile line reached 67,000+ Kbps, smoothly playing 4K videos.

IP Quality and Streaming Unlock

• IP Type: Detected as Public IP, ASN AS979 (NetLab Global), low risk, few shared users.
• Streaming & AI Unlock:
  • TikTok: Unlocked (Canada region)
  • Disney+: Unlocked (Japan region)
  • Netflix: Unlocked (Japan region)
  • YouTube: Unlocked (Japan region)
  • Amazon Prime Video: Unlocked (Japan region)
  • ChatGPT: Unlocked (Japan region)
  • Spotify: Blocked (tested unlockable)
  • Tested Unlocks: Claude, Gemini, Grok and other AI services work normally.

Summary: This VPS has excellent unlock capabilities. Except for Spotify (which is unlockable in practice), it unlocks almost all mainstream streaming and AI services, a major advantage for relevant users.

Review Summary

Based on all tests above, conclusions are as follows:

Advantages:

1. Strong hardware: AMD EPYC 7452 CPU with excellent performance, NVMe SSD with impressive I/O speed.
2. Excellent network: Fully optimized outbound and return routes for China Telecom, Unicom, and Mobile, with low latency and high stability.
3. Outstanding unlock capabilities: Wide support for streaming and AI services, high-quality IP.
4. High cost-performance: Annual plan provides very competitive hardware and network quality at this price point.

Disadvantages:

1. No SLA guarantee and non-refundable: May be risky for new users or those seeking guaranteed service stability.
2. Mobile network speed fluctuations: Despite CMI return, some regions may not perform as steadily as Telecom and Unicom.

Recommended Users:

BitsFlowCloud Japan Tokyo Mainland-Optimized VPS is ideal for users who require high server performance and high-quality China-Japan network connections. Whether for personal websites, learning, game acceleration, or acting as a proxy for international internet access, it offers excellent experience. Its strong streaming and AI unlock capabilities make it a fully featured “tool.”

If you are looking for a high-performance, cost-effective Japan VPS and can accept its non-refundable policy, this product is definitely worth considering.
