Detailed Review of tudcloud's US VPS: Mandatory Three-Network AS4837 + DDoS High Protection

Hostjiceping previously reviewed cmivps' US VPS before it was merged into [tudcloud] (Simple Review: cmivps US Seattle Three-Network China Unicom AS4837 Route VPS). Due to its provision of three-network AS4837 direct connection back to China and free 20Gbps DDoS protection (upgradable to 200G for an additional $5), it's excellent for website hosting and other purposes. After 3 years, Hostjiceping wants to see how this Seattle three-network AS4837 + DDoS protected VPS performs under tudcloud's management. Still focusing on mainland China users, we'll pay close attention to latency, routing paths, bandwidth performance during peak hours, IP unlocking capabilities, performance benchmarks, and more...

KVM virtualization, three networks forced through AS4837, default 1Gbps bandwidth, 2*e5-2699v3, DDR4, SSD RAID10, comes with one IPv4, free 20G DDoS protection (upgradeable to 200G);

8G memory comes with 3 IPv4s, 10G memory comes with 5 IPv4s

The server uses e5-2699v3 CPU (single socket 18 cores/36 threads, base frequency 2.3GHz/boost 3.6GHz), KVM virtualization at the underlying level. The administrator has enabled BBR, supports IPv4 & v6, upstream network provider is spartanhost, located in Seattle on the US West Coast. Current I/O testing shows approximately 200MB/s:

FIO read/write test results are as follows:

IPv4 IPERF3 multi-node test results:

IPv6 IPERF3 multi-node test results:

SpeedTest.Net bandwidth and latency test data for some international nodes:

SpeedTest.Net bandwidth and latency test data for some Asian nodes:

IPv4 streaming service unlock test results:

IPv6 streaming service unlock test results are poor:

VPS performance benchmarks are as follows:

Summary:

The current VPS host server load is not high, and performance is acceptable;

IPv4 is a broadcast IP, but can unlock TikTok/ChatGPT etc.; IPv6 is native US IP, but unlocking performance is poor;

Due to cnservers having extensive China Telecom/Unicom/Mobile bandwidth access in Los Angeles, plus DDoS protection, this is quite an ideal approach among non-premium routes.
