Hong Kong VPS evaluation by yerhost

yerhost is a Chinese hosting provider and a new business that started engaging in IDC business this year. According to the introduction of VPS Island, the boss is an old webmaster. He first rented servers for his own use, and then slowly started selling hosts among friends. Only this year did he start opening new domain names to the outside world. However, judging from the domain name, it is also an old domain name.

This article will conduct a daily evaluation of Hong Kong Telecom’s professional VPS under yerhost. If you are interested, you can go to the official website: https://www.yerhost.com.

After using the discount code: summer, the minimum monthly payment is 64 yuan. It is no problem to put it on a personal blog or website.

From the background, we see that the XenSystem management system is used. Basically all Chinese hosting providers use this system, so let’s just live with it.

Judging from the IP, it should be a rented machine from Anchang Network (51idc). In terms of network, it is relatively excellent. So, let’s take a look at the Internet first. This is the national ping.

And route tracking in various regions

There is also our local long-term ping, which can be said to have no packet loss.

Because the bandwidth is only 2Mbps, there is no need to test the network speed, but as a courtesy, let’s wget a file from mainland China. From wget’s point of view, there should be no limit to 2Mbps for inbound access, because the speed has already exceeded the outbound speed of our machine. The station bandwidth is up (10Mbps).

That's the case, let's wget another mainland China file,

Then let’s test outbound as well.

Then let’s start looking at the performance of the machine.

This is how hard disk reading and writing works:

I originally planned to use DD to test the IO of the hard drive, but I decided to use hdparm.

First install,

yum install hdparm -y

Then use the following command to find the drive letter of the disk

fdisk -l

Finally test it

hdparm -Tt /dev/xvdb1
