Sometimes Google’s files reveal internal information. Here’s some debug info for Google Search: it looks like many search features are actually server-side plugins and Google measures the time taken to load them. There are plugins for social posts, knowledge panels, rich snippets, product ads, forum clusters, Gmail results, health results, hacked sites, hashtags, empty results, science links, Korea features and more. The debug information is provided by a Java plugin (JvmInfoPlugin).
