One of the most surprising things people notice when testing SHONiR CMS is its performance. Many developers ask the same question:

How can SHONiR CMS handle extremely high traffic and deliver web pages so fast, even on an average or low-end server?

In real-world testing, SHONiR CMS has been able to handle 100,000+ requests efficiently on modest server configurations – even on shared hosting environments. The secret behind this performance lies in its smart caching architecture.

Instead of modifying the core of CodeIgniter 4, SHONiR CMS simply uses its built-in capabilities in a smarter and more optimized way.

Respecting the Power of CodeIgniter 4

SHONiR CMS does not modify any core files of CodeIgniter 4.

This is intentional.

CodeIgniter has a very strong development team behind it and is one of the most stable and reliable PHP frameworks available today. Rather than altering the framework, SHONiR CMS focuses on utilizing the full power of CodeIgniter in the best possible way.

The goal is simple:

• Keep the framework clean and maintainable
• Use native features efficiently
• Help developers build projects faster

The 3-Layer Cache System in SHONiR CMS

To achieve extremely fast performance, SHONiR CMS uses three different caching layers.

1. PHP Web Page Cache
2. HTML Static Cache
3. Image Cache Optimization

Each layer reduces server workload and improves response time.

---

1. PHP Web Page Cache (CodeIgniter Built-in Cache)

The first layer uses the built-in caching feature provided by CodeIgniter 4.

This caching system stores the generated output of a page, allowing the server to deliver the same page quickly without rebuilding it every time.

This built-in feature works extremely well and provides significant speed improvements.

You can learn more about CodeIgniter’s page caching here:

2. HTML Static Cache (Ultra-Fast Page Delivery)

The second caching layer in SHONiR CMS is HTML static caching.

In this method, the CMS generates a fully rendered HTML version of a page and stores it directly on the server.

When a visitor requests the page:

• The system does not connect to the database
• No PHP processing occurs
• The server directly delivers the static HTML file

This approach dramatically reduces server load.

All generated HTML cache files are stored in:

writable/cache/htmls

This method is particularly useful for websites where content rarely changes, such as:

• Business websites
• Product catalogs
• Service websites
• Company portfolios

For such sites, content might remain unchanged for months or even years. In those cases, repeatedly querying the database to rebuild pages is unnecessary.

SHONiR CMS handles this intelligently by serving pre-generated HTML pages instantly.

Example of SHONiR CMS HTML Cache

You can see an example here:

https://8.shonir.com/shonir-cms/bpd17/multi-cdn-guide-boost-website-speed-performance.html

If you open the page source, you will see something like this at the top:

<!-- SHONiR Cache generated: 03/08/26 15:07:42 UTC -->

At the bottom of the page you will find:

<!-- SHONiR Cache loaded Time: 03/08/26 23:35:12 PKT Usage:659.19 kb Peak:659.73 kb -->

• When the page request was processed
• The memory usage for the request
• Peak memory usage

This provides transparency for developers and helps monitor performance.

How to Enable Web Page Caching in SHONiR CMS

To activate the CodeIgniter web page cache, follow these steps:

1. Open your database in phpMyAdmin
2. Locate the table:

   tbl_config

3. Search for the config key:

   cache_time

If the value is

0

, caching is disabled. Set a value like

300

for 5 minutes cache duration. Example values:

Value	Meaning
300	5 minutes
900	15 minutes
3600	1 hour

This setting controls CodeIgniter's built-in web page caching.

---

How to Enable HTML Cache

To enable HTML static caching, open the

.env

file in the root directory of SHONiR CMS. Find this line:

html.cache = false

Change it to:

html.cache = true

Once enabled, SHONiR CMS will automatically generate static HTML pages and store them in the cache directory.

---

3. Image Cache Optimization

The third layer of caching focuses on image performance.

SHONiR CMS automatically:

• Converts images to WebP format
• Compresses image files
• Reduces file size while maintaining visual quality

This results in faster page load times and reduced bandwidth usage.

---

How to Enable Image Cache

To enable image caching:

1. Open table

   tbl_config

2. Find the key:

   cache_image

3. Set its value to

   true

To control image quality, find

image_quality

and set values from 0–100. Example: 85 provides a good balance between image quality and file size.

---

Important Note About Global Cache Time

The

cache_time

setting acts as the global cache control. If

cache_time = 0

, HTML caches will be removed after generation. This value affects multiple cache systems, including image caching behavior.

---

Why This Caching Strategy Works So Well

By combining multiple caching layers, SHONiR CMS drastically reduces:

• Database queries
• PHP processing
• Server CPU usage
• Memory consumption

The result is a system that can serve massive traffic even on low-cost hosting environments. This is why SHONiR CMS can achieve exceptional performance without requiring expensive infrastructure.

---

✔ Clean architecture
✔ Zero modification of CodeIgniter core
✔ Multi-layer caching system
✔ Optimized image delivery
✔ High performance even on shared hosting

All these factors together make SHONiR CMS a powerful and efficient platform for building fast websites.
