We’re very grateful to Cromwell Business Systems, who were kind enough to share their experience of load testing with NCC Group last year.
It’s a great success story and a good example of how meticulous planning makes all the difference. In particular, Cromwell left themselves plenty of time to test, make adjustments to the platform, and retest.
In this quarter’s survey of the UK’s top 50 retail sites, we found that, on average, home pages were a little slower than in Q1. We also noticed a strong correlation between page speed and third-party content.
Web pages tend to be image heavy these days, often sporting product galleries and whole-page background images. New, high-resolution displays also now support higher quality imagery than ever before.
As a result, images are increasingly the performance bottleneck. Not necessarily because their optimisation is overlooked more often than other best practices, but because failing to optimise them can have a disproportionate impact on performance.
