Hi,

today I am releasing the very first version of localmemcache (version 0.0.1).
Localmemcache is a library written in C that offers efficient sharing of a
hashtable between processes on a local Unix machine by taking advantage of
shared memory. Its Ruby binding aims to be similar to that of the MemCache
Ruby bindings.

* http://localmemcache.ruby...

EXAMPLE
=======

require 'localmemcache'
$lm = LocalMemCache.new :namespace => "viewcounters"
$lm[:foo] = 1
$lm[:foo]
$lm.delete(:foo)

PERFORMANCE
===========

Here's a quick speed comparison, made on an
Intel(R) Xeon(R) CPU E5205 @ 1.86GHz:

Benchmark pseudo code:

2_000_000.times {
index = rand(10000).to_s
$hash.set(index, index)
$hash.get(index)
}

MemCache: 253326.122 ms
LocalMemCache: 6055.552 ms
Ruby's Hash: 4963.313 ms

So in this example localmemcache is about 40 times faster than using memcache
locally, and about 20% slower than Ruby's hash.

INSTALL
=======

# gem install localmemcache
