nginx - 调整 nginx worker_process 以获得每分钟 100k 次点击

Question

我们有一台服务于一个 html 文件的服务器。

现在服务器有 2 个 CPU 和 2GB 内存。从 blitz.io 来看，我们每分钟获得大约 12k 个连接，在 60 秒内有 200 个超时，每秒有 250 个并发连接。

worker_processes  2;

events {
 worker_connections 1024;
}

如果我增加超时，响应时间就会开始增加到超过一秒。

我还能做什么来从中榨取更多汁液？

Answer 1

配置文件:

worker_processes  4;  # 2 * Number of CPUs

events {
    worker_connections  19000;  # It's the key to high performance - have a lot of connections available
}

worker_rlimit_nofile    20000;  # Each connection needs a filehandle (or 2 if you are proxying)


# Total amount of users you can serve = worker_processes * worker_connections
