使用apache-jmeter-5.2.1做压力测试，下面是压测日志信息1：

Answer 1

如果是linux服务器，可以尝试修改下nginx配置文件 nginx.conf 的参数

events {
        use epoll;         #使用epoll 的I/O 模型
        worker_connections 65535;     #每个进程允许的最多连接数
        multi_accept on;
}

#优化服务器名字的hash表大小
http{
………..
server_name_hash_max_size 64；
server_names_bucket_size 64；
……….
}

#设置超时时间
http{
………..
    sendfile        on;
        tcp_nodelay on;
    keepalive_timeout  65;
    client_max_body_size 20M;
    client_header_buffer_size 16k;
……….
}

最后也可以给页面加个缓存
