Magento Site Performance Optimization

Starting with the Right Hardware
In the preceding command, your.magento.store.com is the default address of the
store you want to test. We chose to stress the display of all the items belonging to the
living-room category in order to perform a lot of database and PHP treatments.
The following results were not very encouraging:
Concurrency Level: 5
Time taken for tests:
Complete requests: 100
Failed requests: 83
110.396 seconds
(Connect: 0, Receive: 0, Length: 83, Exceptions: 0)
Write errors: 0

As you can see, the time per request is 5519 ms. In other words, we have to wait
almost 6 seconds in order to visualize the living room page.

Evaluating your needs
Before choosing your hardware, you should know how any changes will directly
impact the performance of your website. In the following sections, we will
successively change the available amount of RAM and the number of CPU, and we
will even over-stress our hard drives.
