景安快云VPS评测

Kuaiyun has been upgraded recently, and the configuration has doubled, but the price remains unchanged, and it still attracts many friends. Recently, we saw that they are running another 50% off first payment campaign. For enterprise user certification, 50% off for first payment, and for personal certification, 30% off for first payment. I believe it can also attract many people.

We happen to have an old version of Kuaiyun and don’t plan to renew it, so I’m writing an omelette review for everyone’s reference. Because it's from mainland China, I don't test the network performance very much. Anyway, it's 1M bandwidth, so I can't test anything.

We are more accustomed to centos, so we should install centos first.

The biggest pitfall of Jing'an is that you need to queue up for reinstallation. I didn't expect there to be a lot of people at this point, okay, just wait slowly (today is November 5, 2015)

Well, today is November 7, 2015, and I’m still in the queue. Let’s check out Master Lu first.

This is the speed of downloading Master Lu

Other tests will have to wait.

Because I had been waiting in line, I had no choice but to send a work order and asked customer service to help reinstall it, and it was installed quickly.

Hard drive IO is beautiful.
