PHP 7.4.0 Benchmarks

PHP 7.4.0 GA stable release is out now. Centmin Mod 123.09beta01 LEMP stack has been updated to support PHP 7.4. I posted some comparison benchmark for REMI Yum vs Centmin Mod built PHP binaries for PHP 7.4 vs 7.3 vs 7.2 vs 7.1 vs 7.0 with and without Profile Guided Optimizations on Centmin Mod community forums here. Below is preview of 1/3 PHP 7.4 benchmark charts shown from the full benchmark results here.

Centmin Mod site & forum Progressive Web App (PWA) Conversion

I am a self confessed page speed optimisation addict so when I started reading up on Progressive Web Apps (PWA) and using service worker caching and precaching, I got all excited by the possibilities of making my sites and forums load pages even faster :) On July 22, 2018 I…

Improving Nginx Zlib Compression Performance

As part of this How to boost Centmin Mod LEMP stack performance guide, I did some benchmark comparisons for each of the supported Centmin Mod Nginx compiler build options for GCC 4.8.5, 5.3.1, 6.3.1, 7.2.1, 8.0 and Clang 3.4.2, 4.0.1, 5.0.1, 6.0.0 with the standard default Nginx Zlib library versus Cloudflare’s Zlib performance fork library. I did load testing benchmarks using my own custom forked version of wrk load testing tool testing gzip compressed requests so as to properly test each Zlib library https://github.com/centminmod/wrk/tree/centminmod.

Nginx Benchmarks After CentOS Linux Kernel Page Table Isolation Fixes

Most recent Linux Kernel updates have been to address Meltdown & Spectre vulnerabilities. The first Linux Kernel patch update was to address Meltdown and reportedly it can result in between 5–30% performance overhead while others report it at 5–20%. I decided to do my own tests on CentOS 7.4 64bit OVH dedicated server running Centmin Mod 123.09beta01 branch LEMP stack with Nginx 1.13.8 to see how the updated CentOS 7.4 3.10.0–693.11.6 Linux Kernel impacted Nginx static file serving performance with PTI enaabled vs PTI disabled (no Retpoline Kernel fixes are available in CentOS Linux Kernel as yet).

Linode StackScript Centmin Mod LEMP Stack Install

A Linode StackScript allows you to customise and automate your Linode VPS server deployments. I’ve created an official public StackScript for my Centmin Mod LEMP stack installation for CentOS 7. You can follow the development on official forums here. There are optional extras you can choose to customise your Linode VPS server deployments including adding your Pushover.net email so you can get a push notification alert to your mobile devices when the StackScript completes it run.

Letsencrypt SSL Integration Beta Testing Begins

Centmin Mod LEMP stack’s newest addon, acmetool.sh is about to begin public beta testing allowing Nginx users to auto generate new Nginx vhost sites with HTTP/2 based HTTPS support out of the box with free Letsencrypt SSL certificates :) What is addons/acmetool.sh ? Basically, addons/acmetool.sh is a standalone Centmin Mod Addon added to Centmin Mod 123.09beta01 branch which extends the feature set of Centmin Mod to allow users to automatically create Nginx based vhost site domain accounts and automatically obtain and configure the site to use free domain validated Letsencrypt SSL certificates and serve your site(s) via Nginx HTTP/2 protocol based HTTPS. It is one of the last remaining pieces needed before pushing Centmin Mod 123.09beta01 branch to stable release.
