Which of the following is NOT identified as a top finding in the Waterfall analysis?

The correct choice identifies a finding that is not typically emphasized in the context of a Waterfall analysis. The primary objective of Waterfall analysis is to provide insights into the loading performance of web resources, focusing on aspects that can immediately impact user experience and website performance.

Uncompressed text resources are indeed a critical topic in Waterfall analysis, as compressing text files can significantly reduce load times. Similar attention is given to resources with cache rates lower than 50%, since effective caching is essential for minimizing load times on subsequent page visits. Additionally, third-party or CDN resources that slow down loading times are crucial to identify in order to optimize overall performance.

On the other hand, while resources larger than 1MB can impact load performance, the threshold of 1MB isn't typically a standard cutoff in the same way that issues like compression or caching are highlighted. The focus tends to be more on specific optimization techniques rather than just the size of resources unless they exceed substantially large limits that are well beyond typical performance standards. This makes the identification of resources larger than 1MB less critical in the context of Waterfall analysis compared to the other findings listed.
