与Redis相比，memcached是恐龙吗? [英] Is memcached a dinosaur in comparison to Redis?

问题描述

过去几周我在 memcached 上做了很多工作，刚刚发现了 Redis.读到他们自述的这部分，我的胃里顿时有种暖暖的舒服的感觉:

I have worked quite a bit with memcached the last weeks and just found out about Redis. When I read this part of their readme, I suddenly got a warm, cozy feeling in my stomach:

Redis 可以用作类固醇的 memcached，因为它与memcached 但有许多功能更多.和 memcached 一样，Redis 也支持给键设置超时时间此密钥将自动在给定的时间内移除通过.

Redis can be used as a memcached on steroids because is as fast as memcached but with a number of features more. Like memcached, Redis also supports setting timeouts to keys so that this key will be automatically removed when a given amount of time passes.

这听起来很神奇.我还发现这个页面有基准:http://www.ruturaj.net/redis-memcached-tokyo-tyrant-mysql-comparison

This sounds amazing. I'd also found this page with benchmarks: http://www.ruturaj.net/redis-memcached-tokyo-tyrant-mysql-comparison

那么，老实说 - 与这个名为 Redis 的新人相比，从性能角度来看，memcache 真的是一个糟糕的选择吗?

So, honestly - Is memcache really that old dinousaur that is a bad choice from a performance perspective when compared to this newcomer called Redis?

我以前没有听说过很多关于 Redis 的事情，因此我的问题的方法！

I haven't heard lot about Redis previously, thereby the approach for my question!

推荐答案

Memcache 仍然是一个出色的工具，而且非常可靠.

Memcache is an excellent tool still and VERY reliable.

而不是从谁更快的角度来看待这个问题 <100 ms 范围，看软件每个类"的性能.

instead of looking at this issue from the perspective getting down the who is faster at the < 100 ms range, look at the performance per "class" of the software.

• 它是否只使用本地内存?-> 最快
• 是否使用远程内存?-> 快
• 是否使用内存加硬盘 -> 哦，嗯.
• 是否只使用硬盘 -> 运行！
