8Cloud Technology 8xen US VPS Review

8Cloud Technology, a hosting provider in mainland China, provides computer room VPS, servers and other products in Hong Kong and the United States. According to their introduction, they have been engaged in related business since 2011, but started active promotion probably in 2016.

A more distinctive meaning is that the host of 8 Cloud Technology has limited bandwidth but no traffic limit, which means that commercial Internet products are difficult to abuse bandwidth and are more suitable for personal Internet or website use.

I received an invitation from 8 Cloud Technology to write a review on their American products. The machine tested this time is a dual-core 512M memory, SSD solid state drive, 5M bandwidth, which is the lowest configuration.

From the perspective of the CPU, it can be seen that the third-level cache is enabled, which is a rare merchant who has enabled the third-level cache.

Baidu Encyclopedia introduces the third-level cache as follows:

The application of L3 cache can further reduce memory latency and improve processor performance when computing large amounts of data. Reducing memory latency and improving large-data computing capabilities are helpful for games. In the server field, adding L3 cache still has a significant improvement in performance. For example, a configuration with a larger L3 cache will use physical memory more efficiently, so it can handle more data requests than a slower disk I/O subsystem. Processors with larger L3 caches provide more efficient file system cache behavior and shorter message and processor queue lengths.

Simply put, if you turn it on, it will be much better.

It was originally supposed to be a comprehensive network test, but for some reason, during the test, the speed of Linode's UK computer room was extremely slow, only a few tens of KB. After waiting for a long time, there was no progress, so I had to abandon the test and use speedtest instead.

speedtest Beijing Unicom

speedtest Guangdong

speedtest Sichuan

speedtest Zhejiang

speedtest default computer room

And return route tracing

There is also the 55 Internet speed test that we are all more concerned about

From all aspects, except for the hard disk reading and writing, which is slightly poor, everything else is excellent, especially the CPU with three buffers turned on, which is an unexpected surprise.
