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.
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
