#review# Luobo Cloud – xen 2-core 1G 60G hard drive G port Phoenix City

I have quite a bit of free time today, and I received a vps trial provided by Luobo Cloud! Using xen virtualization technology, the data center is in Phoenix, and the consulting boss uses G port access. Let’s take a brief look at the specific performance! This review mainly focuses on the XEN architecture and the official financial idcsystem panel!

Get started with a quick look!

1. CPU parameter information

2. Memory and hard disk

[root@MyCloudServer ~]# df -h

Personally, what I think is good is that the system disk is 10G and the data disk is 50G. This arrangement is still good

3. Hen hard disk I/O test 4. VPS network performance test

Download one of the VPS using WDCP as an example, and download the other with a commonly used speed as an example! It can be seen that commonly used foreign downloads of 100M take almost a second, and the bandwidth of Hen is still sufficient!

5. Other hardware indexes

The data disk tested on this site has been bound. You can install AMH directly without loading the data disk!

[root@MyCloudServer ~]# fdisk -l

The newly opened vps host data disk has been loaded by default and can be used directly! But partners who use WDCP need to modify it to WWW!

That’s it for simplicity. There is basically no problem for ordinary small sites, but you still have to pay attention to the long distance between foreign networks and mainland China, and network fluctuations are normal! Friends who have used foreign hosts know better!
