如何在 Apache Bench 中生成 1Gbps？

如何解决如何在 Apache Bench 中生成 1Gbps？

我有一个带有 16GB RAM 的 i7 处理器（8 核）
我已经安装了 Windows Docker
我已经创建了一个 Ubuntu docker 实例
在 Ubuntu 实例中，我安装了 Nginx（8 个工人）
在 Ubuntu 实例中，我安装了 Apache Bench (ab)
在 Ubuntu 实例中，我设置了如下所示的高 ulimit 值

# 个 ulimit 值

root@c8c1c6a106c2:/# ulimit -a
core file size          (blocks,-c) 0
data seg size           (kbytes,-d) unlimited
scheduling priority             (-e) 0
file size               (blocks,-f) unlimited
pending signals                 (-i) 24682
max locked memory       (kbytes,-l) 82000
max memory size         (kbytes,-m) unlimited
open files                      (-n) 1048576
pipe size            (512 bytes,-p) 8
POSIX message queues     (bytes,-q) 819200
real-time priority              (-r) 0
stack size              (kbytes,-s) 8192
cpu time               (seconds,-t) unlimited
max user processes              (-u) unlimited
virtual memory          (kbytes,-v) unlimited
file locks                      (-x) unlimited
root@c8c1c6a106c2:/#

现在，当我运行以下 ab 命令时，在 Ubuntu 实例中，我只得到 137.73 KBytes/sec (1.1MBits/sec)。虽然我的网卡可以支持10Gbps，但为什么吞吐量很低，我该如何改进？
