Magento has a default built in cache management system that when enabled caches system data such as configuration, layouts, blocks, translations etc.

The default cache storage code uses the file system, i.e. Whilst this will certainly improve Magento responsiveness there are other cache storage options available that are much faster and there are additional types of data we can also cache to improve the overall responsiveness and speed of a Magento CE application.

For most computer systems the fastest data storage medium is the physical memory, using memory as cache storage results in very quick data access times and Magento can get it’s data much quicker.

# # If unsure: # use "activerehashing no" if you have hard latency requirements and it is # not a good thing in your environment that Redis can reply form time to time # to queries with 2 milliseconds delay.

# # use "activerehashing yes" if you don't have such hard requirements but # want to free memory asap when possible.

The most important settings are the TCP port numbers used for each instance, the process id, log file name and persistence data.

Redis can be configured to automatically save (or persist) cached data to disk, this is really useful for volatile cache data, i.e. Essentially redis saves a dump of the cache data regularly to disk (in /var/lib/redis) so that if the redis instance crashes or the server is restarted the cached data is not lost.

At the time of writing this will install redis v2.8.4. We want to enable three Magento cache types : system, session and fpc (full page cache), whilst all three cache types could use one redis storage instance there are some issues where it is safer to give each cache type it’s own redis storage instance.

This also allows us to specifically configure redis options for each cache type, for example we can configure volatile session data to be redis persistent.

You must at least make the tcp port numbers and pids unique.

In computing, active data is often cached to shorten data access times, reduce latency and improve input/output (I/O).
