Chapter 1. PHP goes to the enterprise level

Vulcan Logic's Script Running Machine, SRM, was first conceived in the autumn of 2000. It is designed to solve some of the problems often encountered within web scripting languages (i.e. PHP) that are a result of the stateless nature of the HTTP protocol.

SRM utilizes various methods to cope with the problems presented to programmers, such as the direct caching of variables from supported scripting languages. This approach offers a considerable increase in speed over a database-only solution, mainly due to speed the SRM system keeping the values in memory.

Another feature of SRM is it's ability to handle all persistent database connections, offering a significant advantage in a variety of situations. The SRM system can give a developer the ability to support the use of multiple scripting languages, or the ability to control the number of connections spawned to a database server more effectively. The SRM system does not spawn a connection to a database server for each individual connection, but rather it can decide if it is worth the overhead or if it is better to share another connection.
