justg provides Japanese vps service, based on KVM virtualization by default, pure SSD array, 500Mbps bandwidth (actually 1Gbps). According to the official statement, "Chinatelecom premium Routing Access to China directly, lowest latency Fastest Speed connect Europe and all over the world", so how effective is justg's Japanese vps? Is it suitable for use in mainland China environment? Is China Telecom's high-end router the CN2 you think it is? Please see the webmaster’s evaluation details!

KVM virtual, pure SSD raid10 array, comes with an IPv4 (native), free IPv6 (also native), the written bandwidth is 500Mbps, and the actual measured bandwidth is 1Gbps. Since the monthly payment price is more expensive, the annual payment price is listed below!
| Memory | CPU | SSD | Traffic | Price | Purchase |
| 512M | 1 core | 10G | 500G/month | $50/year | Link |
| 1G | 2 cores | 20G | 1T/month | $100/year | Link |
| 2G | 3 cores | 40G | 2T/month | $200/year | Link |
| 4G | 4 cores | 80G | 3T/month | $300/year | Link |
| 8G | 5 cores | 160G | 4T/month | $400/year | Link |
| 16G | 6 cores | 240G | 5T/month | $1000/year | Link |
| 24G | 7 cores | 320G | 6T/month | $1200/year | Link |
The CPU model is e5-2695v2 (main frequency 2.4GHz, acceleration frequency 3.2GHz, dual-channel 24 cores, 48 threads), justg's own AS, the current hard disk I/O is approximately 204MB/S:
The approximate data of the FIO test are as follows:
The official website states a bandwidth of 500Mbps, but the actual test result is 1Gbps. Below is the speed test data of speedtest.net’s three network nodes in mainland China:
During the evening peak, the backbone network is blocked. Let’s take a look at the network test data at night:
I ran it twice when I didn’t pay attention to the test, so I posted it:
speedtest node test data in Asia:
Test data of speedtest international nodes:
iperf3 tested several European and American nodes, the approximate results are:
The files stored on the test chicken, Guangzhou Unicom's home bandwidth, the download speed is roughly as follows:
In the evening peak period, when the backbone network is blocked, the download speed is roughly as follows:
In the evening peak hours, China Unicom in Meishan, Sichuan, the download speed is as follows:
At evening peak, Hubei Shiyan Telecom, the download speed is roughly as follows:
Delay data of multiple nodes of the three networks in mainland China:
Outbound telecom: take the SoftBank route
China Unicom’s outbound journey: SoftBank too
Mobile outbound journey: CMI direct connection
Telecom return trip: Take the China Unicom direct line back to China
China Unicom return trip: Take the SoftBank line to return to China
Mobile return: direct mobile connection back to the country
Tiktok Unlocked: Japan
Unblocking some cross-regional streaming media: Netflix, chatgpt, etc. are available
Some Japanese streaming media unlocking tests:
VPS performance test:
A rough summary:
Currently, VPS performance is weak and not suitable for higher-intensity load tasks, but simple website building is still possible;
In terms of network, both China Telecom and China Unicom use Softbank, and China Unicom direct connection is used for the return trip. China Mobile uses its own direct line for the outbound and return journey! The three networks are all directly connected, with low latency and good speed. The IP can unlock tiktok, Netflix, chatgpt, etc. It is still useful and worth trying!
