Joomla! Performance on Steroids
This document summarizes a presentation on optimizing Joomla performance. It describes two parts to the presentation: Part 1 covers basic application-level optimizations for Joomla like keeping Joomla updated, choosing extensions wisely, simplifying templates, and using plugins and .htaccess rules to enable caching and compression. Part 2 discusses server-level optimizations like using a CDN, opcode caching with APC and Memcached, and reverse proxy servers like Nginx and Varnish. It provides configuration examples and presents results of benchmark tests showing improvements from optimizations.

- 45. Some Key Takesfrom part 1 Speed optimization is a process – do it regularly and you will be rewarded. Always test! Don’t test on a live site, use staging copy instead! Backup! Choose a well optimized host
- 46. TAKE A BREAK backin 5!
- 47. PART 2 Let’s getour hands dirty
- 48. Cloud, VPS orDedicated? Cloud – can be both awfully slow and cheap or super fast and really expensive, highly scalable VPS – Usually fast and inexpensive, but you’re dependent on others on the same box, limited scalability Dedicated – usually expensive and fast, not easily scalable CHOOSING THE METAL
- 49. Hardware matters! SSDdrives for MySQL & Cache SSD Capable File System, if dedicated RAID for files RAM for Caching CPUs that support virtualization BACKUP! BACKUP! BACKUP!
- 50. We need toinstall some software on it: 1. Web Server 2. MySQL 3. PHP with Cache 4. Memcached 5. Static and Reverse Proxy server NOW THAT YOU HAVE YOUR BOX
- 51. Web server choice WEBSERVER CHOICE
- 52. ★ Apache Pros Easy to setup and support, hundreds of modules, free Supports Joomla! out of the box Can be found on 99% of the webhosts preinstalled Apache Cons Apache does not scale well and is resource heavy Apache has limited number of concurrent users Apache is generally much slower than NginX in every aspect Apache is the obvious choice.. Or is it?
- 53. Timeout 30 KeepAliveTimeout 10 MaxKeepAliveRequests30 StartServers 20 MinSpareServers 10 MaxSpareServers 20 ✔ Remove all unused apache modules, this reduces the request processing time. Apache recommended settings
- 54. ★ NginX Pros Shorter response times compared to apache Very high number of concurrent users Faster than Apache in serving static content Supports FastCGI NginX Cons Not supported by major control panels (cPanel, Plesk) Does not support mod_rewrite out of the box – additional configuration for Joomla! NginX for performance PHP
- 55. Joomla SEF URLson NginX Add this code to nginx.conf file: MORE INFO AT: http://is.gd/qCeuqU # Support Clean (aka Search Engine Friendly) URLs</tt> location / { try_files $uri $uri/ /index.php?q=$request_uri; }

- 57. 1. Most buffersin MySQL are per connection. They store pointers, NOT data. 2. Optimize your InnoDB - separate the data files - increase innodb_thread_concurrency (not more then the amount of cores you have) 3. Optimize your query cache. MYSQL SETUP TIPS

- 61. 1. Install APC: peclinstall apc 2. Load APC extension in PHP: /usr/local/lib/php.ini - extension=apc.so Recommendation: Keep the default settings! Enable APC
- 62. Enable Memcached 1. InstallMemcached (service) yum install memcached 2. Install PHP Memcached module pecl install memcache 3. Recommendation: configure Memcached to use Unix domain socket instead of TCP – improves speed! /usr/bin/memcached -d -m 64 -c 2049 -P /var/run/memcached/memcached-11211.pid -s /tmp/memcache.sock

Joomla Patch forUnix Socket Connecti ons Edit the following file: libraries/joomla/cache/storage/memcache.php Change the code on lines 86-88 from self::$_db->addServer($server['host'], $server['port'], $this- >_persistent); $memcachetest = @self::$_db->connect($server['host'], $server['port']); To: self::$_db->addServer('unix:///tmp/memcache.sock', 0); $memcachetest = @self::$_db- >connect('unix:///tmp/memcache.sock', 0);
- 65. Move PHPbinaries to RAM Move TMP to RAM Move MySQL to an SSD drive or SSD RAID array Enable MySQL query cache Use TMPFS for MySQL’s tmpdir Install Google PageSpeed for apache Enable Gzip compression (mod_deflate on apache 2) More Apache/MySQL/PHP Tweaks
- 66.
- 67. Also knownas Reverse HTTP Proxy Install it in front of any server that speaks HTTP Blazing fast – usually speeds up 300-1000x Performance is usually bound by the speed of LAN Free, Open Source software Varnish - The ultimate web app acceler ator
- 68. Can beharder to setup and configure than NginX You still need Apache (or NginX, varnish does not know PHP) Dramatic performance increase – only when caching dynamic content Caching dynamic content might lead to unexpected troubles!!! Cache should be properly invalidated!!! Varnish Cons
- 69. Varnish VCL? Excludenon-cacheable pages: • registration form • administrator • installation folder Set objects expiration time
- 70. Sample Varnish JoomlaVCL joomla.vcl: # Bypass Varnish if the request is to the registration form if (req.url ~ "task=registration.register" || req.url ~ "view=registration") { return(pipe); } # Never cache administrator/installation if (req.url ~ "/administrator" || req.url ~ "/installation") { return (pass); } return (lookup); ---- sub vcl_recv { set req.backend = default; include "joomla.vcl"; if (req.url ~ ".(png|gif|jpg|swf|css|js)([?].*)?$") { return (lookup); }
- 71. How we tested? We use Siege - http://www.joedog.org/siege- home/ Siege command: siege -b -t 60S -f urls.txt -c 20 We use 20 number of simultaneous connections We use a predefined list of URLs – all URLs from the default Joomla main page + sample data We measure the number of hits taken for 60 seconds TEST THE OPTIMIZATIONS
