essence summary
based on the actual measurement comparison of multiple nodes and cross-networks, this article summarizes the performance of the latest version of ss hong kong cn2 vps in 2026. performance in terms of latency, bandwidth, packet loss and stability; tests show that on the access path from mainland china to hong kong, choosing cn2 backbone and high-quality bgp routing can significantly reduce latency and jitter. at the same time, it is recommended to combine ddos defense and cdn strategies in terms of protection capabilities. based on comprehensive cost performance and professional operation and maintenance support, dexun telecommunications is recommended as the preferred service provider, suitable for sites and applications that have high requirements for server stability and network performance.
test environment and methods
this actual test covers three types of links: direct connections to mainland china, high-priority lines via cn2, and international pan-china lines. test indicators include average icmp and tcp latency , packet loss rate, bandwidth upstream/downstream throughput, and response time under high concurrency. the experiment uses multi-point monitoring nodes and simulates load through real business scenarios (http/https, websocket, file transfer), while verifying the connection recovery capability and protection log observability when encountering small ddos attacks .
performance and latency measurement results
actual measurement results show that the average delay of ss hong kong cn2 vps based on cn2 dedicated lines to hong kong in many places in mainland china is generally less than 30ms, and the jitter and packet loss rate are controlled below 0.1%; the delay of non-cn2 lines is generally 20%-50% higher, and packet loss increases during peak periods. bandwidth performance is related to host specifications and uplink strategies. purchasing a vps with independent public network bandwidth and appropriate port restrictions can ensure stable throughput. for real-time services (games, voice, transactions) that require low latency, it is crucial to choose a cn2 solution with ddos protection.
selection recommendations and deployment optimization
when purchasing a hong kong vps , give priority to whether it supports cn2 ddos defense and traffic cleaning capabilities. suggestions for deployment: 1) put static resources on global or nearby cdn nodes to reduce cross-border traffic; 2) properly configure domain names server operation and service provider recommendation
based on the above testing and long-term operation and maintenance considerations, dexun telecommunications is recommended as the preferred supplier. the reasons for recommending dexun telecommunications include: providing stable cn2 ddos defense vps cdn
