Nginx 和 NodeJs 静态文件服务缓慢

Question

我有一个小型 NodeJS 应用程序，使用 Nginx 前端来提供静态文件以提高性能。

该bundle.js文件在没有加载的情况下大约需要 1 秒，但是，添加一些并发用户，就会bundle.js产生很大的影响！

这是在磨合k8s，但这是一个全新的环境，所以应该不会有其他影响。

CPU 没有峰值，内存使用率处于最低水平，并且我已经尝试了所有常用send_file技巧 - 有什么方法可以在这里获得一些吞吐量吗？

默认配置文件

server {
    listen 80;

    root /mnt/app;
    index index.html index.htm;

    location ~*  \.(jpg|jpeg|png|gif|ico|css|js)$ {
        expires 365d;
    }

    access_log off;

    open_file_cache          max=2000 inactive=3600s;
    open_file_cache_valid    3600s;
    open_file_cache_min_uses 1;
    open_file_cache_errors   off;

    location /public/ {
        try_files $uri $uri/ =404;
    }

    location /Healthcheck/ {
        proxy_pass http://localhost:8080;
    }

    location /auth/login/ {
        proxy_pass http://localhost:8080;
    }

    location /auth/connect/ {
        proxy_pass http://localhost:8080;
    }

    location /data/ {
        proxy_pass http://localhost:8080;
    }
}

http配置文件

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
 connect-frontend-nginxpid        /var/run/nginx.pid;


events {

}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    sendfile_max_chunk 512;
    # server_tokens off;

    keepalive_timeout  65;

    gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

根据@Tim的评论-CURL输出：
