在网络上,你可能会看到Memcached 的性能比 Redis 更强,但延迟才是最关键的指标。 更高的延迟意味着网页加载更慢,最终影响用户体验。 尽管Redis 具有丰富的功能,但你真的需要它们吗? Redis 集群难以扩展和维护,你可能需要不断添加新的分片(shard)并进行重新平衡。 通常,很多人一开始自己管理 Redis,但随
本内容是对知名性能评测博主 Anton PutraRedis vs Memcached Performance Benchmark内容的翻译与整理, 有适当删减, 相关指标和结论以原作为准 在本视频中,我们将对比Redis和Memcached。我会介绍一些功能上的不同,但主要关注性能。 首先,我们会衡量缓存系统最重要的指标之一---延迟(latency),使用p99 百分位数。缓存系统...
Redis offers comparable performance for simple caching tasks and additional features for more advanced use cases. It enables asynchronous and non-blocking I/O operations, allowing your application to handle more concurrent tasks. This functionality enhances its performance under heavier workloads. Redis al...
To answer your original question: The performance and memory usage of Redis compared to memcached should berelatively similar. Close enough that for most uses any performance difference in either direction is academic as neither is likely to be the bottleneck. Unless you already have a large invest...

找到原因就容易解决了。重新调整Memcached的启动参数,增加-c参数来提高连接数量。默认为1024,可以逐步增加以找到最佳数值。我设置为2048。 启动命令为: memcached -d -m 256 -c 2048 -l 127.0.0.1 -p 11211 -u root 如果服务器充裕,可以考虑分布式的memcached集群,以降低单个节点上的压力。
前些年,HandlerSocket的横空出世让人们眼前一亮,当时我还写了一篇文章介绍了其用法梗概,时至今日,由于种种原因,HandlerSocket并没有真正流行起来,不过庆幸的是MySQL官方受其启发,研发了基于InnoDB的Memcached插件,总算是在MySQL中延续了NoSQL的香火,以前单独架设Memcached服务器不仅浪费了内存,而且还必须自己维护数据的不...

ElastiCache for Redis提供具备自动故障转移的多可用区域以及增强的健壮性。 Memcached 高性能、分布式内存对象缓存系统,旨在加速动态Web应用程序。 有人使用/比较过两者吗?它们之间的主要差异和用例是什么? 谢谢。 - Joe 2 https://aws.amazon.com/elasticache/redis-vs-memcached/ - kenlukas...
redis 等kv认为内存该放热的,cloudflare 则认为内存该放冷的,两者都是正确的,redis的客户需要内存性能,整体内存比例偏高,performance优先,cloudflare的cdn cache不太追求内存性能,ssd比例偏高,cost优先。 总结就是:传统内存缓存开始做一些闪存的feat,那么反过来,本来是给闪存做的持久性kv,用作缓存,效果怎么样呢?这就是...
