By your request, we have changes the manner of cache deletion used upon the performance of a POST request. For now, we have deleted cache for the entire page that originated the POST. Imagine that we have to handle a very large news archive. Each news item is written to memcache with a validity period of 24h or more. If a new comment was placed under any of those records, the memcache was cleared for all records. This solution may be useful from time to time, but not for a news site with several thousands of records, as the TYPO3 CMS runs needlessly.

Amazon Web Service is a set of various services. Their scope is so wide that we couldn’t possibility describe them in a few sentences. My everyday work, however, would not be possible without two of them.
S3 – Simple Storage Service, which I will describe in another article on Content Distribution Networks in TYPO3 CMS.
EC2 – Elastic Compute Cloud – used to test various configurations of any implemented solution. In your average conditions it is hard to test the application’s behaviour on e.g. 6 different servers.

TYPO3 cache
The TYPO3 performance issue is often a subject of discussion. I found a number of various tricks, which can speed up the page generation time, including nc_staticfilecache and dmc_highperformance modules. The latest alpha version of TYPO3 contains radical changes in the caching mechanism, enabling us to choose from various support functions, such as file, memcache, database or apc.
Problem
All of the above solutions, with the exception of nc_staticfilecache, have one thing in common: in order to read cache, one has to invoke a php process, read and parse the cached data, and then send the information to the browser.
Let’s perform a simple test using the ab tool. We will check the number of queries per second for a complex Web site.
