Recently, I came across a Raksmart email promoting their Double 11 event, and I found a Japanese VPS that I thought had a good price. So I decided to buy one and do a simple test to provide reference for friends in need.

Double 11 Event VPS

Event Time: 11/01/2022~11/30/2022 (San Jose time, USA). They are offering several popular VPS deals with the following prices and configurations:

When purchasing, the displayed price is the original price. It will automatically apply the discount code JPHKVPS2048-5.99dis on the checkout page to show the discounted price. If you choose the annual payment option, you will get a discount of 2 months. For new users, please provide accurate and real information when making the purchase to avoid being flagged by the risk control system.

Server Test

Here is the server information:

The disk I/O test results show an average I/O speed of only 67.6 MB/s, which is quite poor.

 I/O Speed(1st run) : 67.4 MB/s
 I/O Speed(2nd run) : 68.5 MB/s
 I/O Speed(3rd run) : 66.9 MB/s
 I/O Speed(average) : 67.6 MB/s

The bandwidth is heavily restricted, with no redundancy, and both upload and download speeds are limited.

Node Name        Upload Speed      Download Speed      Latency     
Speedtest.net    5.00 Mbps         5.00 Mbps           129.25 ms   
Los Angeles, US  4.78 Mbps         4.75 Mbps           177.81 ms   
Dallas, US       4.91 Mbps         4.94 Mbps           225.77 ms   
Montreal, CA     4.94 Mbps         4.84 Mbps           265.35 ms   
Paris, FR        4.91 Mbps         5.19 Mbps           218.53 ms 

In the Super Ping test, the average latency within China is 80ms, which is acceptable.

Routing Test

For Beijing Unicom, the outbound route directly connects to Japan via Softbank's network, which is quite good.

For Sichuan Telecom, the outbound route goes directly to Japan via Guangdong, using BGP routing:

For Guiyang Mobile, it seems to go to Hong Kong and then to Japan:

Returning to Sichuan Telecom surprisingly takes the CN2 network route??? (I'm not sure if it's ICMP optimization)

Furthermore, it is unknown if there will be any network adjustments in the future. The above results are for reference only.

Conclusion

The Raksmart Japanese VPS that xiaoz purchased has poor disk performance and heavily restricted bandwidth. The network performance is acceptable, and other aspects will be updated later after using it for a while.

Note: Raksmart has a history of data loss, so important data should be regularly backed up.
