This document discusses frameworks in web development and introduces Phalcon as a high performance PHP framework. It summarizes that frameworks provide application structure but can slow performance due to additional files loaded on every request. Phalcon addresses this by being written as a C extension, avoiding PHP parsing overhead. Benchmarks show Phalcon's faster file includes, lower memory usage, and faster response times compared to traditional PHP frameworks. The document provides instructions for installing Phalcon and encourages further learning on its website.

2. What is a Framework?
● Web Development Library
● Application Skeleton
● Proven Functionality
● Hopes and Dreams of
a Developer

3. The Problem
with Frameworks
● Speed
● Complexity
● Resources

4. PHP as an
Interpreted Language
➔ Receive Request (from Apache/Nginx)
➔ Read file from HHD/SSD
➔ Parse file
➔ Compile into OpCodes
➔ Execute through Zend Engine
➔ Render Output

5. Back to the Problem with
Frameworks
● Framework design requires
many files
● PHP lifecycle runs for every
file called during runtime
(without caching)
● Framework load happens
for EVERY request
