CHI::Benchmarks - Benchmarks of CHI and non-CHI drivers
VERSION
version 0.54
DESCRIPTION
These benchmarks were created by running
etc/bench/bench.pl -d . -t 10 -x
for CHI 0.42, on OS X v10.6.6, 2.2 GHz Intel Core 2 Duo, Perl 5.12.2.
For each cache, bench.pl does repeated gets and sets of a data structure for at least 10 seconds and measures the wallclock time per
operation.
These numbers should just be used as a rough guideline! Actual results will vary widely depending on system, get/set pattern, actual values
being set, the proper tuning of memcached/mysql, etc. For best results run the benchmark script (available in this distribution) on your
own system.

VERSION
version 0.14
SYNOPSIS
use CHI;
my $cache = CHI->new(
driver => 'Memcached', # or 'Memcached::Fast', or 'Memcached::libmemcached'
namespace => 'products',
servers => [ "10.0.0.15:11211", "10.0.0.15:11212", "/var/sock/memcached",
"10.0.0.17:11211", [ "10.0.0.17:11211", 3 ] ],
debug => 0,
compress_threshold => 10_000,
);
DESCRIPTION
A CHI driver that uses Cache::Memcached to store data in the specified memcached server(s).
CHI::Driver::Memcached::Fast and CHI::Driver::Memcached::libmemcached are also available as part of this distribution. They work with other
Memcached clients and support a similar feature set. Documentation for all three modules is presented below.
CONSTRUCTOR OPTIONS
Namespace, appended with ":", is passed along to the Cached::Memcached::* constructor, along with any constructor options not recognized by
CHI - for example servers, compress_threshold and debug.
If you need more control over the options passed to Cache::Memcached::*, you may specify a hash directly in "memd_params".
METHODS
Besides the standard CHI methods:
memd
Returns a handle to the underlying Cache::Memcached::* object. You can use this to call memcached-specific methods that are not
supported by the general API, e.g.
$self->memd->incr("key");
my $stats = $self->memd->stats();
UNSUPPORTED METHODS
These standard CHI methods cannot currently be supported by memcached, chiefly because there is no way to get a list of stored keys.
dump_as_hash
clear
get_keys
get_namespaces
is_empty
purge
