# tun-bench matrix behind the macOS numbers on pandafan.app/pandacore (SagerNet/tun-bench, run as root).
# Point `version` at your PandaCore binary: an absolute path is used as a local build, while tun-bench
# downloads the open-source engines itself. Run three rounds with reversed implementation order in
# round two and a 30-second cooldown between rounds; retain all rounds and aggregate by median.

补丁让 tun-bench 把本地路径当作 PandaCore 二进制、按 PandaCore 的配置格式写 TUN 段，并把测试网段挪到不与 PandaCore 默认地址冲突的位置。
