Gunicorn 在某些页面上将 CPU 使用率飙升至 100%...降低性能

Question

我有一个通过 Nginx/Gunicorn 提供服务的 Django 应用程序。在加载某些页面时，Gunicorn 的 CPU 使用率会飙升至 100% 并完全降低性能，导致页面加载时间为 10 秒。

我没有进行任何数据库调用 - 我已经加载了所有结果memcached。它应该非常快，所以这种疯狂的减速是疯狂的。

gunicorn_start：

NAME="name"                                  # Name of the application
MAINDIR=/opt/name/
DJANGODIR=/opt/name/path             # Django project directory
SOCKFILE=/opt/name/run/gunicorn.sock  # we will communicte using this unix socket
USER=nginx                                       # the user to run as
GROUP=nginx                                      # the group to run as
NUM_WORKERS=3                                     # how many worker processes should Gunicorn spawn
DJANGO_SETTINGS_MODULE=name.settings             # which settings file should Django use
DJANGO_WSGI_MODULE=name.wsgi                     # WSGI module name

nginx.conf：

user  nginx;
worker_processes  8;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


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

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                      '"$http_user_agent" "$http_x_forwarded_for"';

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

    sendfile        on;
    #tcp_nopush     on;

    gzip_disable "MSIE [1-6]\.";

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

这被部署到远程测试服务器。我尝试将NUM_WORKERSin设置为gunicorn_start1、3、9 和 17，但无论如何问题仍然存在。

当我关闭manage.py runservergunicorn 并使用 .
