  • Performance is a Journey, not a Destination Posted on October 20th, 2010 by Catchpoint Systems

    No one likes slow websites or websites that malfunction. Today, time is very valuable – and no user wants to be frustrated trying to access a website. We all have better things to do than wait for a webpage to load or keep hitting the reload button on the browser in hopes the problem will […]

  • The Boy Who Cried Wolf in Web Performance Posted on October 11th, 2010 by Catchpoint Systems

    Today, performance monitoring involves monitoring the performance, reliability, and availability of every object on the website, including third party vendors, as any of these objects can cause performance problems to the page.

    Slow web performance is the new downtime – it’s the silent killer to an online brand.

Response, or the time it takes to load an […]

    Availability, or Uptime, is one of the most important metrics for web performance monitoring, however it is often misunderstood and defined incorrectly. Availability is simply the percentage of time your site, application, or service works successfully. The problems in defining Availability arise from defining what is considered “success” and what is considered “failure”. In the case an […]

  • Monitoring the Performance of 3rd Party Providers (CDNs, Ad Servers, Widgets…). Posted on July 20th, 2010 by Catchpoint Systems

    The SLA (Service Level Agreement) topic is already well covered – books have been written and libraries filled on this subject- so I will try to avoid writing a book of my own.
