When your servers are hurting
And your database needs some relief
Something small, simple and efficient
Can make your response times brief
Sometimes, you don't need anything fancy
You just need something good
My friend is lightweight and speedy
And he does exactly what he should
Keys and values
Hashes and slabs
And viola! it all just works
So go forth, apply caching
And let your servers rest.
Because any sysadmin will tell you,
memcached is the best.
