memcached

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

Redis

A persistent key-value database with built-in net interface written in ANSI-C for Posix systems.

CSQL Main Memory Database and Cache

CSQL Cache is updateable bi-directional table level caching solution which improves application performance by 20 to 100 times. It can also be used as ultra fast stand alone Main Memory Database. Enterprise edition at http://www.csqldb.com

Ruby Memcache

A Ruby client library for memcached, a high-performance distributed memory cache. memcached is used to alleviate database load by caching oft-used values in network-accessible memory space, and is used behind several high-traffic dynamic web sites like LiveJournal, Slashdot, WikiPedia, and others.

Memcached Providers

This project provides Memcached Session State and Cache Providers for ASP.net.

php-object-cache

PHP Object Cache is a Memory Object cache, implemented with PHP Sockets. It runs on PHP4 or PHP5+ and requires your PHP build to have sockets enabled. There are numerous memory caches available, that definitely will have better performance and implementation: http://www.danga.com/memcached/ ... [More] http://www.php.net/manual/en/book.apc.php http://eaccelerator.net/ http://xcache.lighttpd.net/ However, they are not implemented in pure PHP, they require php extensions, and installing the object cache separately. PHP Object cache should work even on shared hosting, if your host allows Socket deamons. This is mainly the reason I wrote it, so it can be deployed from within your PHP app without any setup if other memory caches are not available. UsageStart the PHP Object Cache socket deamon via the command line: /usr/bin/php -c /path/to/php.ini socket.phpOr start the socket deamon from within PHP: exec('/usr/bin/php -c /path/to/php.ini socket.php > log.txt &');The & option makes the process run in the background, so your PHP script can continue on. Example for windows in in create-socket.php Then in your PHP code, import the PHP Object Cache client. // require client class require_once('client.class.php'); // create a connection to the server $Cache = new Socket_Cache_Client('127.0.0.1', 9803); // set a value $Cache->set('test', 'This is a test'); // retrieve a value $test = $Cache->get('test');At the moment this is all you have. NotesPHP Object Cache is implemented as a single deamon process. It does not fork other processes simply because support for forking processes and IPC would require PHP extensions. Therefore it will not efficiently use multi-processors. PHP Object Cache uses socket_select() which uses the select() system call. So its efficiency will be dependent on that an how PHP implemented select(). This is the only "event notification" available in native PHP. At the moment the Object Cache cannot be distributed across servers. You can run an object cache on a separate machine, but it will be independent of other caches. If you know of a better alternative or was of implementing those noted please let me know. Tests and BenchmarksWe will be adding some test here soon. DownloadThe code is very alpha, minimally tested. Get the source from subversion repository and do your own tests before trying it out. [Less]

cachestatus

Cache Status Add-On for FirefoxDescriptionThis add-on adds a customizable presence to your browser window's statusbar that gives you up-to-date information on your browser's cache usage, both RAM and the hard drive. The presence also has a right-click context menu, where you can easily clear ... [More] your browser's cache. It can also automatically clean your cache when it reaches a specified level, through its Options. NotesThis extension does not have any influence on or from Firefox's own memory consumption in your OS. The reported statistics are entirely independent. A fresh profile usually doesn't have the RAM "maximum" capacity (stored in the browser.cache.memory.capacity preference), so you may see it blank. If so and if you set it to something, it will forever create that maximum, barring some prefs.js hacking of your own. Firefox does some sort of dynamic calculation if this isn't set, so use that with caution. In a future version, I may add a 'delete' button to the settings to restore it to "factory settings." You can also put in "-1" to give Firefox back the "reins." More info Some comments talk about it not working - please try it with a fresh profile. If that doesn't work or you need help with that, contact me. If it does work, then it's most likely a conflict with one of your other extensions or themes. Please submit bug reports using the Issues tab. Thank you for checking it out! [Less]
