Hi,<br />
I'm trying to better understand how memcache's slabs work. Currently I'm storing thousands of very small items in memcache, and many are expiring way too soon. When I look at the stats, it shows memcache still has plenty of available memory.<br />
<br />
So I'm wondering.. When memcache receives an item, and decides it should go into slab 7, does it evict items in slab 7 if that slab is full , even though memcache itself still has plenty of available memory? Or does it create a new slab, and store the item in there, leaving the existing items in slab 7 untouched?

Memcache and Slab Size

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Components

MySQL is an open source, relational database management system that runs as a server providing multi-user access to a number of databases. Acquired by Oracle in 2009, it is frequently used in combination with PHP installations, powering most of the WordPress installations.
