Cache::Memcached::Fast is a Perl client for memcached, a memory cache daemon. Module core is implemented in C and tries hard to minimize the number of system calls and to avoid any key/value copying for speed. As a result, it has very low CPU consumption.

API is largely compatible with Cache::Memcached, the original pure Perl client, most users of the original module may start using this module by installing it and adding "::Fast" to the old name in their scripts (see "Compatibility with Cache::Memcached" section in the module documentation for full details).

The module does not depend on any external library, it contains custom memcached client implementation in C designed for efficient interaction with Perl (actually client code has well defined generic API and may be used by itself).

The module should compile and work on any Unix-derived system. Win32 support is based on the patch by Yasuhiro Matsumoto---thanks!, and is (expected to be) supported by community. Note: on Win32 below Windows Vista max number of memcached servers is 64. See comment on FD_SETSIZE in src/socket_win32.h to learn how to increase this value if you need to connect to more than 64 servers.

Despite the low version number (which mainly reflects release history) the module is considered to be beta (see BUGS below on how to report bugs). See "Compatibility with Cache::Memcached" section in the module documentation for the description of what is missing compared to Cache::Memcached.

To install this module type the following:

perl Makefile.PL
make
make test
make install

Don't forget to start the memcached daemon on local host port 11211 (the default) before running make test.

You can find documentation for this module on CPAN. Or, after installing, with the perldoc command:

perldoc Cache::Memcached::Fast
