WordPress Hosting Optimization

We've put a lot of effort into determining how to get the most speed, stability and security out of WordPress. We're confident our Secure Isolated Platforms are the fastest WordPress hosting plans available. Adding our optional Content Delivery Network will speed things up even more.

Hardware

  • Dell R410 Server
  • Dual Intel quad-core server with Intel 5600 Series Westmere processors
  • 256KB L2 cache per core
  • 12MB L3 Cache per CPU
  • 1066Mhz front side bus
  • Up to 24GB DDR2-FBDIMM 667Mhz memory
  • 15K SAS Hard Drives in RAID 10 Configuration
  • 15,000RPM Spindle speed
  • Battery-backed hardware SAS Raid controller with 256MB write Cache

15K SAS Hard Drives in RAID 10 configuration provides zero read/write contention between drives and tagged command queuing for highest performance over traditional SCSI or SATA drives. RAID 10 for fastest read/write performance. RAID 10 is a stripe of mirrors offering full data redundancy without the need of costly parity calculation.

15,000RPM Spindle speed provides fastest read/write access and data transfer at 3.0Gbit/s per drive to the SAS controller.

Database Performance Tuning

  • Percona Server with XtraDB is used on all WordPress plans
  • Database data is stored on a 15K SAS disk RAID 10 filesystem with a battery-backed caching RAID controller
  • Perconas my.cnf variables have been specifically tuned for WordPress

Security Enhancements

  • The OBP server has all unnecessary services disabled both for performance and security.
  • Nightly YUM updates keep all libraries and packages up to date with latest available versions.
  • The system kernel is kept up to date utilizing Ksplice live kernel updates. No reboots required.
  • Custom built latest stable PHP 5 version is installed and upgraded as needed.
  • All WordPress servers come with APF (Advanced Policy Firewall) configured with optimal rulesets for WordPress.
  • SSH Access is limited by ip access restrictions.

Operating System-level Tuning

  • System Integrity Monitor (SIM) watches all critical system services.
  • All Kernel variables have been optimized for highest system performance.
  • The system disk scheduler has been adjusted for best performance with the hardware raid controller.
  • System networking variables are optimized for throughput and set to ignore source-routed, spoofed, and redirected packets.

Web Server Optimization

  • PHP open_basedir is disabled for as it can hurt PHP performance.
  • PHP caching is handled by eAccelerator PHP accelerator, optimizer, and dynamic content cache on WP-OBP-100, WP-OBP-200, and WP-OBP-300 plans. WP-OBP-400 Plans and OBP clusters utilize APC for PHP caching.
  • PHP Realpath cache settings are increased
  • Apache KeepAlives are enabled and tuned for efficiency.
  • Gzip output compression is enabled
  • A secure Memcached instance in setup to be used with W3 Total Cache. This allows the WP cache to utilize ram for caching instead of the filesystem.

Network Optimization

  • Fully burstable 1000BaseT uplink
  • BGP Version 4 redundant network serviced through 4 separate carriers
  • Our network consists of enterprise level Cisco Catalyst 6500 series equipment for both our core and distribution

Backup Strategy

  • Redundant secure backup systems
  • Continuous data protection. We backup your site files using R1Soft's Server Backup Manager. Backup copies are kept in two locations, one on your server and the second on a remote backup server
  • MySQL database data backed up nightly for all plans
  • Backed-up data is retained for up to thirty days
