Sharktech: $129/month/2*E5

How is sharktech? Is sharktech good? Sharktech (Shark Computer Room), as a very well-known old brand computer room in the United States, has always been famous for its own DDoS defense. As the Chinese market becomes larger and larger, there are more and more customers. , the sharktech computer room is also connected to China Telecom, China Unicom, and China Mobile lines. Due to budget issues, I have never had the opportunity to test it. Here I got a 1Gbps bandwidth promotional server from the Shark Los Angeles computer room. I will test it for everyone. I hope that the data shared will be useful to you!

Server package:

10Gbps bandwidth-unlimited traffic

Dedicated server, optional in the United States (Los Angeles, Denver), Netherlands (Amsterdam), 10Gbps bandwidth, (shared) unlimited traffic, comes with 5 IPv4, free 60Gbps DDoS defense.

All evaluations of the four major computer rooms:

Los Angeles: Sharktech: $129/month/2*E5-2678v3/64GB memory/1TB NVMe hard drive/unlimited traffic/1Gbps-10Gbps bandwidth/DDOS/Los Angeles computer room simple evaluation

Chicago: sharktech: Simple evaluation of Chicago computer room 1Gbps bandwidth unlimited traffic server

Denver: sharktech: Shark Denver computer room 1Gbps bandwidth server, simple evaluation

Netherlands: sharktech: A simple evaluation of the 1Gbps bandwidth unlimited traffic server in the Dutch computer room

The test machine is a dual-channel e5-2678v3 (24 cores, 48 ​​threads), 64G memory, 1TB NVMe, a centos7.7 system is installed, the webmaster has enabled BBR, and the hard disk I/O is roughly 944MB on average: < /p>

FIO test, beautiful data

The following mainly uses speedtest nodes in mainland China. We can see that the uplink bandwidth in mainland China can reach up to 538Mbps, and the downlink bandwidth can reach up to 930Mbps:

iperf3 runs in Europe and the United States, with a maximum uplink of 942Mbits and a maximum downstream of 942Mbits:

Data from 146 detection points in mainland China provided by ping.chinaz.com:

Outward journey test!

The outbound telecom connection is directly connected to the backbone network, and Shark connects it himself to 100G:

The outbound journey to China Unicom is also directly connected to the backbone network, and Shark himself also connected to China Unicom:

Moving there is a fixed mode, still exporting from Guangdong, and then CMI International goes directly to the computer room:

Return to China Telecom: Straight from the computer room to return to China, nothing extra

Return to China Unicom: take Unicom AS4837 (VIP) back

Return to China Mobile: We found that part of the information was hidden. All we could see was AS58453 connecting to AS9808. The obvious one in the Guangzhou direction was cogentco directly connecting to AS9808

To sum up the down trip and return trip, since it is not a high-end line, so:

(1) For the outbound journey, China Telecom is a direct backbone connection, as is China Unicom, and China Mobile can also be regarded as such,

(2) Return, AS4134 China Telecom direct, AS4837 China Unicom direct, China Mobile are slightly worse and less optimized

In the end, Unix bench, it may be a script problem. There is an error when running multi-core. I can only look at the single-core score. It’s okay:
