#启动进程,通常设置成和cpu的数量相等

#As a general rule you need the only worker with large number of
#worker_connections, say 10,000 or 20,000.
#
#However, if nginx does CPU-intensive work as SSL or gzipping and
#you have 2 or more CPU, then you may set worker_processes to be equal
#to CPU number.
#
#Besides, if you serve many static files and the total size of the files
#is bigger than memory, then you may increase worker_processes to
#utilize a full disk bandwidth.

#
#一般一个进程足够了,你可以把连接数设得很大。如果有SSL、gzip这些比较消耗CPU的工作,而且是多核CPU的话,可以设为和CPU的数量一样。或 者要处理很多很多的小文件,而且文件总大小比内存大很多的时候,也可以把进程数增加,以充分利用IO带宽(主要似乎是IO操作有block)。
#
#根据我配置实践,服务器是“多个CPU+gzip+网站总文件大小大于内存”的环境,worker_processes设置为CPU个数的两倍比较好。
#eg: 2个4核CUP, 则设置为8或者16.
