Boost magento performances managing the two level cache

MagentoIf you are after some improvements on magento “speed”, you will probably interested in why it is so slow, a great explanation about why (a piece at least) magento is slow, is detailed here.

To sum it up, assuming you are using memcached to store the sessions (and I hope you do), here a small snippet to be applied to your app/etc/local.xml file to handle that second level cache:


As it is in the snippet, the second level is stored in the database instead of writing everything in the files as it does by default, using this (after restarting memcached) you will notice a huge boost in speed, you can also disable it by setting the slow_backend_store_data to 0, but that will slow down a lot the website when the cache is empty.
