django – uWSGI没有释放内存

我发现uwsgi进程没有释放内存.在这张来自newrelic的图表中,你会发现uwsgi进程所占用的内存仍然停滞在~100MB左右,尽管在这种停滞期间,网站/应用程序一直没有活动.

另外,仅供参考：app / uwsgi进程开始时只耗费56MB.当我用ab(apache基准测试)进行测试并且用-n 1000 -c 10或大约该范围进行测试时,我达到了这个~100MB.

Nginx Conf

server 
{
      listen        80;
      server_name   <ip_address>;

      root        /var/www/mywebsite.com/;
      access_log  /var/www/logs/nginx_access.log;
      error_log   /var/www/logs/nginx_error.log;

      charset             utf-8;
      default_type        application/octet-stream;
      tcp_nodelay         off;
      gzip                on;

      location /static/ 
      {
        alias /var/www/mywebsite.com/static/;
        expires 30d;
        access_log off;
      }

      location / 
      {
          include uwsgi_params;
          uwsgi_pass unix:/var/www/mywebsite.com/django.sock;
      }
}

app_uwsgi.ini

[uwsgi]
plugins = python

; define variables to use in this script
project = myapp
base_dir = /var/www/mywebsite.com
app=reloc
uid = www-data
gid = www-data

; process name for easy identification in top
procname = %(project)

no-orphans = true
vacuum = true
master = true
harakiri = 30
processes = 2

processes = 2
pythonpath = %(base_dir)/
pythonpath = %(base_dir)/src
pythonpath = %(base_dir)/src/%(project)

logto = /var/www/logs/uwsgi.log
chdir = %(base_dir)/src/%(project)
module = reloc.wsgi:application

socket = /var/www/mywebsite.com/django.sock
chmod-socket = 666
chown-socket = www-data

更新1：所以看起来,它不是uwsgi,而是保留某些数据结构以便加快处理的python进程.
