GoGrid Performance Improvement for Linux Customers – Action Required

February 13th, 2009 by - 20,937 views

In our efforts to continually improve the GoGrid platform, we have released a new kernel patch for our 64-bit Linux customers which can dramatically improve performance.

NOTE: This update only applies to GoGrid customers. Users of other Linux distributions OUTSIDE of GoGrid should NOT apply this patch.

This kernel patch is relatively trivial to install and under some circumstances will dramatically improve disk drive performance.

To install the kernel patch, log into any 64-bit Linux (RHEL or CentOS) server in your GoGrid cloud that was instantiated before 2/12/09.

From the command line, enter the following command on your 64-bit Linux server:

rm ˆf pviofix.sh ; wget ftp://ftp.gogrid.com/pviofix.sh && bash pviofix.sh

Please note that this will require a reboot of your system. GoGrid strongly recommends you apply this patch to improve your system performance.

If you experience any issues or if you require assistance installing this patch, please contact our Support team at 1.877.946.4743 or log a support case via the GoGrid portal.

We appreciate your cooperation in applying this patch.

  1. Although I think I'd qualify this as a critical bugfix, not a performance improvement. The servers were largely undeployable without it. The fix seems to have resolved issues on our servers.

    Initially there was some difficulty since although I applied the bugfix upon release, I didn't reboot the servers (because the wording didn't seem to indicate it's critical nature). Once the servers were rebooted and the fix took effect our problem went away.

    Yes, fixed the issue. I'm none-to-happy about GoGrid's deployment of the fix, the notice could have indicated it's critical nature and saved me and my client several hours of headache.

      Matthew,

      You're right that we could have handled this better. Myself, Michael Sheehan, and our new Service Team Manager, Tom Blossom are planning how we'll make these kinds of releases better in terms of communicating the bugfix scopes and impact more clearly.

      We really appreciate your patience. In hindsight we realize it was more critical than we previously thought. There were some cases where when we measured the performance where we see very pathological behavior that did not arise in our initial tests.

      Best,

      –Randy
