Varnish is an open source HTTP accelerator designed for content-heavy dynamic web sites. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture. A high level overview of what Varnish does can be seen in the video attached to this web page. Varnish stores data in virtual memory and leaves the task of deciding what is stored in memory and what gets paged out to disk to the operating system. This helps avoid the situation where the operating system starts caching data while they are moved to disk by the application. The principal configuration mechanism is VCL (Varnish Configuration Language), a domain-specific language (DSL) used to write hooks which are called at critical points in the handling of each request. Most policy decisions are left to VCL code, making Varnish far more configurable and adaptable than most other HTTP accelerators. When a VCL script is loaded, it is translated to C, compiled to a sha

Sphinx is an open source search server which combines very fast full-text search with a great scalability. It's growing up fast and we not only inventing new features for full text search itself, but also creating new ways to integrate Sphinx into PHP based applications.If you are not yet using Sphinx, we'll be highlighting some key steps on how to serve Full-Text queries to your PHP based applications from start to finish. If you are an advanced Sphinx Search user, this talk will describe where one can offload MySQL or standard Database functions to Sphinx. From some specific queries one can run on the Sphinx to how to increase both performance and scalability of your applications (web-based or otherwise). Besides tips and tricks centered around integration with PHP/MySQL based applications , you will learn about the recent 2.0.1 release straight from the proverbial 'horse's mouth.' This talk will utilize and focus on real-world examples from installation and
