Why does php + memcache have a very slow response

由 假如想象 提交于 2019-12-11 01:42:52
问题 I have a custom framework with a custom class that handles the database connection, queries, etc. In this database class i've decided to use Memcache to speed up my page response time. I save the data in Memcache like 'query-' . md5($sql_query) = 'SQL results' and then when i need to query the database if i already have this key in Memcache then i'll do a ->get on it and use that value. The problem is that it works ok(ish) in the begining but after a period it begins to slow down

Heroku/Memcache/Rack::Cache Stats

由 此生再无相见时 提交于 2019-12-11 01:38:40
问题 I am trying to wrap my brain around Rack::Cache, Rails 3.2, Memcache, and Heroku. I think I've got it all working together, as outlined here: http://myownpirateradio.com/2012/01/01/getting-heroku-cedar-and-rails-3-1-asset-pipeline-to-play-nicely-together/ All that said, I am unsure if Memcached is actually doing what it should. Is there any way to get stats on Memcached or to see if a request was cached by Memcached? I put the current time on a page, and can see that it is getting cached

Sharing Memcache with PHP and Python

由 a 夏天 提交于 2019-12-10 23:43:24
问题 I am trying to share a Memcache key between Python and PHP. Python writes the key and PHP reads it. I am using the Cakephp framework, with php-pecl-memcache (not php-pecl-memcached), and the python-memcache all python library. Python: mc = memcache.Client( ["127.0.0.1:11211"]) key = "key1" value = 1323779849 mc.set(key, value) PHP: echo Cache::read('key1', 'memcached'); PHP can't read the variable, I get weird "MemcachePool::get() [http://php.net/memcachepool.get]: Failed to uncompress data"

Ehcache Memcache Redis 三大缓存男高音

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Ehcache 在java项目广泛的使用。它是一个开源的、设计于提高在数据从RDBMS中取出来的高花费、高延迟采取的一种缓存方案。正因为Ehcache具有健壮性 （基于java开发）、被认证（具有apache 2.0 license）、充满特色（稍后会详细介绍），所以被用于大型复杂分布式web application的各个节点中。 什么特色？ 1. 够快 Ehcache的发行有一段时长了，经过几年的努力和不计其数的性能测试，Ehcache终被设计于large, high concurrency systems. 2. 够简单 开发者提供的接口非常简单明了，从Ehcache的搭建到运用运行仅仅需要的是你宝贵的几分钟。其实很多开发者都不知道自己用在用Ehcache，Ehcache被广泛的运用于其他的开源项目 比如：hibernate 3.够袖珍 关于这点的特性，官方给了一个很可爱的名字small foot print ，一般Ehcache的发布版本不会到2M，V 2.2.3 才 668KB。 4. 够轻量 核心程序仅仅依赖slf4j这一个包，没有之一！ 5.好扩展 Ehcache提供了对大数据的内存和硬盘的存储，最近版本允许多实例、保存对象高灵活性、提供LRU、LFU、FIFO淘汰算法，基础属性支持热配置
