Is your hosting capacity sufficient?

“Threshold effect”

Sometimes a site is subject to a phenomenon called the “threshold effect”. As the name suggests, this is a situation in which the loading time increases when a given threshold of visits is surpassed.

To ensure that your site does not become affected by the threshold effect, Quanta correlates your loading time with the number of visitors on your site. If your loading time increases when you have more visits, you have threshold effects. If your loading time remains stable during peak traffic, it means that all is working well!

To see this data, go to the performance tab through the features menu

Example of threshold effect

On this site for example, there may be two times when there was a threshold effect . On 24th and 25th June : a stronger increase in traffic generated much slower response times (traffic is represented by the superposition purple curve)

The optimization index: ICC

Does your host capacity remain stable in time? We have created our index, the Infrastructure Cost per Click index. This indicator estimates the capacity of your infrastructure. It is the result of a ratio between the server loading time and the number of pageviews, and it therefore represents the “infrastructural cost of a click on the site.”

This indicator allows you to answer the question: “What is the cost of a click on my server loading time?”

The goal of this chart is to allow you to anticipate issues. If your ICC increases, it means that your host capacity decreases.

It is therefore a chart to monitor specifically during your major sales periods.

Example of a host capacity which decreases

In this example it must have been a change on the website between 28th & 29th May. This results in the capacity dividing by three (if the website could accommodate 30,000 simultaneous visitors before, it can only accommodate 10,000 now).

If that happens on your website, that phenomenon must alert you.  Please contact as soon as possible your partners or Quanta team for more details.
