Yecao host Hong Kong Shatin vps host KVM 1 core 512M 2M bandwidth simple test

When I received the 4th anniversary promotion from Wecao, I saw that the Hong Kong vps host was very affordable, especially the one with 512M memory, which was very cost-effective, so I bought one for my own use! However, for friends who have been building websites for a long time, it is better to choose the 1G memory model. After all, many host vendors now have 1G memory, including Alibaba Cloud and Tencent Cloud, which have removed the 512M memory package hosts. This time, Wecao has launched a Shatian node, which uses KVM virtualization technology. After indirect testing for a while today, we found that it is still good. We are going to set up the environment and put it on a small site to see how stable the host is!

This website purchased a 512M memory package. Here are some simple tests for purchasing a host!

1. Basic configuration information

On-line CPU(s) list: 0

From the basic information, you can see that the memory is 498M, the hard disk capacity is 9.6G, these are normal, the CPU frequency is 2133MHz, there is no limit on the CPU frequency, and there are swap bursts.

2. Download speed test outside mainland China

[root@7vps ~]# wget cachefly.cachefly.net/100mb.test
-bash: wget: command not found
[root@7vps ~]# yum -y install wget

When using the WGET command, it prompts that it is not found, which means that you need to install wget yourself. Enter the command: yum -y install wget and WGET will be automatically installed, so the problem is solved! When testing the download speed, it was found to be pretty good. Of course, this test cannot be conducted for a long time, after all, it still takes up a lot of bandwidth!

3. Simple test of hard disk IO performance

[root@7vps ~]# dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
 4096+0 records in
 4096+0 records out
 268435456 bytes (268 MB) copied, 9.45413 s, 28.4 MB/s

Ordinary hard drives are at a relatively normal level. They are enough for building a website. They are much better than those with a few megabytes. The price cannot be too high!

4. Webmaster Network ping speed test

5. Route tracing

Since it was the chick I wanted to use, I smeared the IP. During the PING test, a few places timed out, which is relatively normal for Hong Kong nodes. Currently, a certain hosting provider in mainland China used by this site sometimes receives text messages reminding a certain node that the monitoring data download has timed out. In fact, it is also a normal behavior!
