6 Scalability Lessons

General Chicken

Jesper Söderlund not only put together a few interesting scalability patterns, he also came up with a few interesting scalability lessons:

  • Lesson #1. Put Smarty compile and template caches on an active-active DRBD cluster with high load and your servers will DIE!
  • Lesson #2. Don't use out-of-the-box configurations.
  • Lesson #3. Single points of contention will eventually become a bottleneck.
  • Lesson #4. Plan in advance.
  • Lesson #5. Offload your databases as much as possible.
  • Lesson #6. File systems matter and can run out of space / inodes.
