你的台式机是Windows系统吧。是否
不是，其实是个树莓派

你试试换电脑跑跑看，
或者跑下:
sysctl -a |grep tcp
检查一下缺省的tcp协议栈内存大小值是多少。

你试试换电脑跑跑看，
或者跑下:
net.ipv4.tcp_rmem = 4096 87380 6291456
net.ipv4.tcp_sack = 1
net.ipv4.tcp_slow_start_after_idle = 1
net.ipv4.tcp_stdurg = 0
net.ipv4.tcp_syn_retries = 6
net.ipv4.tcp_synack_retries = 5
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_thin_dupack = 0
net.ipv4.tcp_thin_linear_timeouts = 0
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_tso_win_divisor = 3
net.ipv4.tcp_tw_recycle = 0
net.ipv4.tcp_tw_reuse = 0
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_wmem = 4096 16384 4194304
net.ipv4.tcp_workaround_signed_windows = 0
初步看起来，应该没啥问题。你换电脑测试的话，效果如何？
