DreamCloud Hong Kong High-Defense Three-Network Optimized Standard-16C32G-StandNet Review

bash <(curl -sL https://Check.Place) -H

AMD EPYC 9655, very strong performance, good I/O, much stronger than my own dedicated server.

Test Method: single-thread TCP protocol

Without testing through a landing node, inbound traffic is limited by the firewall, so I chose RFCHOST HK CTC as the landing node. Speeds peaked around 300Mbps. China Telecom is relatively stable, while China Unicom and China Mobile show cutouts. I am not sure whether the 300Mbps cap and the Unicom/Mobile cutouts are firewall policy, since speed testing is probably not within the expected use case of this kind of high-defense server. Latency on all three networks is first-tier and extremely low.

China Telecom	China Unicom	China Mobile

Telecom premium CN2 return, Unicom return 10099->4837, Mobile return CMI.

Latency to Unicom could not be measured here; refer to the later itdog.cn screenshots, where it can be measured.

Latency is quite low. Telecom and Unicom are relatively stable, while Mobile has noticeably more packet loss and jitter; perhaps that is just CMI.

It appears to connect CTG through Alibaba; it also connects CMI and CUG.

Surely nobody buys such an expensive machine just to watch streaming, right...
