Mozilla.com runs on Drupal
Services – Bouncer (load balancing)
Addons.mozilla.com = “AMO”
 72M hits, 4M page views, 1M user sessions
 Runs on CakePHP
 Infrastructure
 3 datacenters (San Jose, Amsterdam, China)
 Net Scaler hardware (Citrix)
 Web Servers -> memcached, db cluster (my,pg)
 12 nodes each for static, dynamic
 Scaling SUMO (support.mozilla.org)

KB, Forum, wiki (tikiwiki)
Initially only 5 reqs/second
Architecture analysis
Load Tests
Profiling (xdebug + kcachegrind)
270 Queries / page load!
Reduce includes
Now up to 12 reqs/second
DB





Caching, move to innodb
Fix slow queries, add indexes
Now down to 19 queries/page
Duplication – Send selects to slaves, other to master
Logic to make post-update selects on master
 Memcached – Whole-page, sessions
 Scaling SUMO contd.
 Use cron jobs instead of rolling up on certain
pages
 Load Testing (now at 22 reqs/sec)
 Millenium
 Log replay
 https://svn.mozilla.org/projects/webtest
 Peak Download Day Stats





14Gb/s
2Gb/s web traffic
300x spike
Turned off AMO to help
One net scaler failed
Testing With Selenium
 Stefan Priebsch
 Testing – Unit, system, acceptance, integration,
performance, load, usability, security
 Selenium IDE – ide.openqa.org – firefox plugin
 Assertions
 Plugins
 Selenium RC – Remote control, seleniumrc.openqa.org
 PHPUnit integration
 PHPUnit_Extensions_selenium_testcase (can set up using
xvfb)

Continuum, Xinc
 Virtual Machines – Snapshot mgmt
 Side note – Red hat switching to KVM from XEN.
Scaling PHP Application
 Maurice Kherlakian – Bell Canada
 Scalability
 Performance vs High Availability
 Load Balancers – Soft vs hardware
 Session Persistence – Sticky, Sharing
(memcached), Session Clusting in Z. Platform

 Database






DRDB = master-slave, HA, no perf gain
Mysql cluster
