# 决定性对比：找出最能扛的隧道配置。
|
||
#
|
||
# 现状：http2 + ha=2 大约 60~75% 可用。剩下 25% 失败的原因是
|
||
# 到 Cloudflare 美西边缘（sjc/lax）的国际链路丢包。
|
||
#
|
||
# 单协议单通道扛不住，那就试三套：
|
||
# A) http2 + ha=2 现状
|
||
# B) http2 + ha=4 TCP 下多连接不像 UDP 那样互相挤
|
||
# C) http2 ha=1 + quic ha=1 两个进程、两种协议同时挂着
|
||
# —— Cloudflare 会在所有连接间分发请求，
|
||
# 哪个协议当下能通就走哪个
