Improving Performance Levels: Server Upgrades

It's been a busy couple of weeks for BlogPatrol. Last week, we made some major usability enhancements to the signup process to make it easier for new users to signup and install BlogPatrol onto their blogs.

BlogPatrol continues to grow steadily in the new configuration that we launched on May 19. We've reached a point, however, where our current servers are no longer giving the desired levels of service to our users:
  • the web server is becoming unreliable and slow with processing http requests
  • it is taking too long for the database to generate your stats reports
To help bring our system performance back to desired levels, we are upgrading our servers by moving from Woodcrest to Clovertown machines. A snapshot of the old and the new:
  • Old: 2.0 GHz Dual Processor Dual Core Xeon 5130 (Woodcrest) with four cores per machine
  • New: 1.86GHz Dual Processor Quad Core Xeon 5320 (Clovertown) for eight cores per machine for faster overall performance
  • Old: 4 gigabytes of RAM per machine
  • New: 6 gigabytes of RAM per machine
  • Old: 32-bit CentOS operating system
  • New: 64-bit CentOS operating system for faster overall performance
  • Old: 10K rpm SAS hard disks
  • New: 15k rpm SCSI hard disks for faster database reads/writes
We procured the new servers over the weekend of August 18-19, and we are setting up the new machines this week. I'll post an update once we are about to cutover to the new machines.

I was afraid to complain about how slow it is retrieving stats, since it's a free service. But thanks very much for working on this.

Hey! Is the blogpatrol site still down? Will it be up again soon, or should I start looking for an alternative?

Hi phunkyphreak, I apologize for the prolonged downtime. We are working to bring the system back online, hopefully within the next 24 hours (as of the timestamp of my reply). I will be posting updates to provide everyone with changes in status.
