jmemcached is a fast network available cache daemon. It is protocol-compatible with memcached, but written in Java and suitable for applications with portability concerns, where Java is the preferred solution, or for using the memcached protocol in embedded applications with alternate storage engines. Existing clients for memcache work unmodified. It can run as a standalone daemon or be embedded inside an existing Java application.
The AbsTemplate is an extremely simple and lightweight template engine for PHP. It consists only of one file: the base class. You can set your own custom delimiters for variables to use inside template files, use any type of templates you want (that is, the template files can have any extension you want (be it .php, .inc, .tpl, etc...)), display multiple templates per page, cache templates, and choose to assign the content of a template to a variable and, when appropriate, just display its content.
pcu is a set of simple command-line utilities to expose the posix_fadvise and mincore syscalls. pcu-fadvise gives the kernel advice on the access pattern for files. This advice can affect all processes by all users accessing those files. pcu-mincore is used to determine which parts of a file are in cache. These utilties are targeted for Linux 2.6, but may work on other operating systems that support the mincore and posix_fadvise syscalls. mincore is not a part of POSIX, and posix_fadvise is uncommon despite being specified by POSIX.
BitHorde is a fast and lightwheight content distribution system, aimed for high-performance decentralized content distribution. Its key features are high performance, a light footprint, and live streaming. Potential applications range from content delivery networks, including HD streaming setups, to offline-caching filesystems, to file sharing, to distribution of in-game maps or textures.
Stash makes it easy to speed up your code by caching the results of expensive functions or code. Certain actions, like database queries or calls to external APIs, take a lot of time to run but tend to have the same results over short periods of time. This makes it much more efficient to store the results and call them back up later. Stash makes caching easy by providing a wrapper class in front of various backend storage handlers.
CHI provides a unified caching API for Perl, designed to assist a developer in persisting data for a specified period of time. The CHI interface is implemented by driver classes that support fetching, storing, and clearing of data. Driver classes exist or will exist for the gamut of storage backends available to Perl, such as memory, plain files, memory mapped files, memcached, and DBI. CHI is intended as an evolution of DeWitt Clinton's Cache::Cache package, adhering to the basic Cache API but adding new features and addressing limitations in the Cache::Cache implementation.
