 ## Google Axion C4A Arm instances in Google Cloud
 
-Google Axion C4A is a family of Arm-based virtual machines built on Google’s custom Axion CPU, which is based on Arm Neoverse V2 cores. Designed for high-performance and energy-efficient computing, these virtual machines offer strong performance for modern cloud workloads such as CI/CD pipelines, microservices, media processing, and general-purpose applications.

 ## PHP benchmarking using PHPBench
 
-In this section, you will learn how to benchmark PHP performance using PHPBench, a modern and extensible benchmarking framework for PHP applications. You will install PHPBench, run sample tests, and interpret key metrics such as mode time, variance, and throughput.
-You will then analyze the results to understand how your Google Cloud C4A (Axion Arm64) virtual machine performs on common operations like string manipulation and array processing.

 PHPBench is a flexible micro-benchmarking tool designed to measure PHP code performance precisely and repeatably. 
 
-It allows developers to do the following:
+With PHPBench, you can:
   * Measure the execution time of PHP functions or code blocks
   * Identify performance regressions between versions
   * Automate performance testing across CI/CD pipelines
   * Track results over time to detect optimizations or slowdowns
