Nginx和PHP FPM很慢

我的服务器有512 MB内存。 nginx.conf的设置是

user www-data; worker_processes 2; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; #tcp_nopush on; #tcp_nodelay on; keepalive_timeout 3; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # Virtual Host Configs ## upstream php { server 127.0.0.1:9000; } open_file_cache max=5000 inactive=20s; open_file_cache_valid 30s; open_file_cache_min_uses 2; open_file_cache_errors on; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } 

我的PHP FPMconfiguration是

 user = www-data group = www-data pm = dynamic pm.max_children = 50 pm.start_servers = 25 pm.min_spare_servers = 8 pm.max_spare_servers = 40 

我正在使用一个WordPress的网站。 但是太慢了。 我有另一个512 MB的办公室服务器。 它使用的是Apache，比Nginx + phpfpm更快。 我的configuration有什么问题吗？

内存使用

• VPS内存使用 – 有点困惑？
• closures一个虚拟主机的gzip压缩
• nginx SSL子域重写
• nginx负载平衡 – 只有日志服务器失败？
• Nginx的陈旧caching和proxy_cache_path

最好的结果

 open_file_cache max=5000 inactive=20s; open_file_cache_valid 30s; open_file_cache_min_uses 2; open_file_cache_errors on; 

 pm.max_children = 6 pm.start_servers = 2 pm.min_spare_servers = 2 pm.max_spare_servers = 4 pm.max_requests = 50
