Squeeze Maximum Performance from your Hosting Platform


Published on

The presentation covers useful insights and benchmark tests on how the performance (and security) of PHP/MySQL based applications can be significantly improved through different tweaks done at server administration level (Linux/Apache). It also examines several different types of hosting platforms: dedicated, virtual/cloud and shared, and how they can influence the CMS application speed and security.

Squeeze Maximum Performance from your Hosting Platform

  1. 1. Squeeze Maximum Performance from your Hosting Platform Tenko Nikolov CEO at
  2. 2. Why I love this car?
  3. 3. What is behind server performance?
  4. 4. Let’s discuss the speed• Invest in hardwareTest at least 3 different hardware setups before proceeding.Always benchmark performance and reliabilityAdd more RAM and use it on maximum capacity
  5. 5. Speed – Cont’d• Install RAM caching mechanisms  Memcache and APC/Eaccellerator• Install reverse proxy  NginX or Varnish• Virtualization always makes things slower  Resources are shared and at the same time are lost for the Virtual OS too!
  6. 6. Speed – Cont’d• Tweak your software to run faster  Use fast & secure PHP like FastCGI  Move PHP binaries into RAM  Move MySQL to a different hard drive. Use RAID or SSD for lightning fast performance.  If using just one app, tweak MySQL for it!  Keep log files separate and small in size  Move TMP to RAM  Avoid creating unneeded I/O, use CDN if possible
  7. 7. Security & Speed?• Security and Performance don’t come hand in hand, but some things usually help both sides:  Latest OS  Late version of the Linux Kernel  Secure firewall, strong monitoring of access, OS and system files
  8. 8. Performance needs Security Isolate accounts!
  9. 9. 99.9% uptime is achievable!• Invest in integrating a monitoring and automated reaction system.• Keep your server load level at minimum at all times.• If you start overloading your server, its either time to upgrade or to tweak further!

  11. 11. Uptime – Cont’d• Spread the server resources wisely  Never allow a single user to use all of the server resources at any given time. Limit and throttle if limits are reached and prevent overloads.  Whenever there’s a resource problem, react within seconds and not within minutes or hours.
  12. 12. The big Question: which platform? SHARED DEDICATED VPS CLOUD
  13. 13. The common understanding
  14. 14. The picture CAN be different!
  15. 15. Let’s prove this
  16. 16. But what if we add cache?
  17. 17. Some key takes• Shared can be a good platform contrary to the common belief, but not always the right one• If you need custom setup/deep customizations & have a big website -> go for VPS/dedicated• Dedicated/VPS & Cloud can perform better for you if you KNOW how to tweak them
