《Redis is single threaded. How can I exploit multiple CPU/cores?》 redis.io/topics/faq,说明了redis使用单线程的原因: CPU通常并不是Redis的瓶颈,因为Redis通常要么受内存限制,要么受网络限制。比如说,一般在Linux系统上运行的流水线Redis,每秒可以交付一百万个请求,如果你的应用程序主要使用O(N)或O(log(N...
因此，严格地说Redis并不是全面单线程。在Redis官网页做出了解释，它是这样描述的：Redis is single th...
官方FAQ表示,因为Redis是基于内存的操作,CPU不是Redis的瓶颈,Redis的瓶颈最有可能是机器内存的大小或者网络带宽。既然单线程容易实现,而且CPU不会成为瓶颈,那就顺理成章地采用单线程的方案了 Redis is single threaded. How can I exploit multiple CPU / cores? It's not very frequent that CPU becomes your b...

Redis is single threaded. How can I exploit multiple CPU / cores?It’s not very frequent that CPU becomes your bottleneck with Redis, as usually Redis is either memory or network bound. For instance, using pipelining Redis running on an average Linux system can deliver even 1 million requests...
