Nginx+tomcat处理速度问题

落地花开啦 2016-03-26 11:24:38 1548

一个内部的系统,javaEE实现,tomcat6.0,服务器是双核 4G内存,大概350用户
设置的是tomcat最大内存768M。
用了nginx-1.1.10反向代理,发现速度反而被拖累了,没有直接用tomcat快(非常明显),贴出我的配置,大家帮我看看问题出在什么地方:

 #user nobody;
worker_processes 2;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {
include 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 logs/access.log main;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

gzip on;

#cache

upstream backend {

#server localhost:8283;
ip_hash; 
#add for session
#jvm_route $cookie_JSESSIONID|sessionid reverse;
}
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;

location / {

index index.html index.htm;
proxy_pass http://backend;
#newly add

proxy_redirect off; 
proxy_pass http://backend;
} 
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;

}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one

    速度肯定会慢啊,多了一层代理时间啊!!!
    前端加nginx/apache目标不是加快单个请求的速度,而是负载均衡加大并发吞吐量(接入loadbalance到多机),你如果稍微深入做大并发应用就不会得出这样的结论
    当然,nginx用linux版本是推荐的,但是这应该不是问题所在
