What are the reasons why PHP framework is slow?

Common reasons and solutions for slow running of the PHP framework: ORM redundant queries: optimize queries, use indexes and unions, and enable ORM caching. Large view files: Explode view files, enable view caching, enable gzip compression. Too many third-party dependencies: only load necessary dependencies, use the optimizer to shrink dependencies, and use caching to reduce external API calls. Invalid routing: Use route caching, optimize routing configuration, and reduce nested routing and wildcard routing. Database connection issues: Use connection pools to manage connections, optimize queries, and consider using NoSQL databases or caching mechanisms.

The reasons why the PHP framework runs slowly and its solutions

Introduction

PHP frameworks, such as Laravel, Symfony, and CodeIgniter, provide a lot of conveniences that simplify web application development. However, these frameworks can sometimes cause performance degradation. This article will explore common causes of slow PHP frameworks and provide solutions.

Cause 1: Redundant ORM queries

Problem:ORM (Object Relational Mapper) produces redundant or inefficient SQL query, which can significantly reduce performance.

Solution:

• Optimize the query, use indexes and appropriate joins to reduce the number of database calls.
• Enable ORM's caching mechanism so that frequently used query results can be stored and reused.

Cause 2: Large View Files

Problem:Huge view files can cause increased page load times because they generate Lots of HTML and CSS.

Solution:

• Break large view files into smaller manageable components.
• Use the view caching mechanism to store rendered views and reduce repeated rendering.
• Enable gzip compression to reduce the size of HTTP responses.

Cause 3: Too many third-party dependencies

Problem:Introducing too many third-party dependencies may cause the application to become Got bloated and slow.

Solution:

• Load only necessary dependencies.
• Use composer optimizer or similar tool to minify dependencies.
• Consider using caching to reduce multiple calls to external APIs.

Cause 4: Invalid routing

Problem:Invalid routing configuration can lead to unnecessary URL redirections and additional Database query.

Solution:

• Use the route cache mechanism to store the routing table and avoid repeated route resolution.
• Optimize routing configuration to reduce nested routing and wildcard routing.

Cause 5: Database connection problem

Problem:Database connection problems, such as improper pooling or delayed connections, can seriously affect the application Program performance.

Solution:

• Use database connection pool to manage database connections and reduce connection establishment time.
• Optimize database queries to reduce server-side load.
• Consider using a NoSQL database or caching mechanism to relieve database pressure.

Practical case

Scenario:The page loading time of the Laravel application is too long.

Cause:Redundant ORM queries and large view files.

Solution:

• Index-optimize the query and use unions.
• Enable ORM caching.
• Break large view files into smaller components.
• Use view cache.

Results:Page load times were significantly reduced and application performance was greatly improved.
