Unverified85% confidenceFactTime unknown
VPN加密对CPU负载极高，标称WiFi速率不代表VPN速率。1GHz双核ARM大约只能跑50-80Mbps的OpenVPN，要跑满千兆VPN需选带AES-NI硬件加速或四核1.4GHz以上CPU的机型

UnverifiedCPU性能很弱，运行OpenVPN加密时实际吞吐量通常只有个位数到十几Mbps，不适合需要高速VPN连接的用户82% similarUnverified硬件VPN路由器的实际VPN吞吐量远低于标称有线吞吐：例如标称千兆的路由器开启OpenVPN加密后实测常只有50-150Mbps，选购要看厂商标注的"VPN throughput"而非"WAN throughput"79% similarUnverified百元级低端VPN路由器(单核580MHz以下)勉强能建隧道但加密速度不足20Mbps，作为主路由跑VPN会严重卡顿，不建议在千兆宽带下购买入门机型跑全屋VPN78% similarUnverified内置VPN的旅行路由器CPU主频应≥880MHz或双核以上，否则开启AES-256加密后实测速度常跌至20Mbps以下，无法满足视频会议或流媒体需求76% similarUnverified看芯片而非标称速率：搭载骁龙X62/X65基带的下行可达4-10Gbps，而入门级骁龙X55/X12方案实际下行约1-2Gbps，标称峰值速率在弱信号下参考意义有限69% similar
