Extension summary

Analyze keywords

Using the Navigation Timing API, the Simple Performance Bar presents network, server, client and page load times as a group of easy to read bars fixed to the bottom of your browser. Each time your page loads, the Simple Performance Bar appears.

Network, server and client time calculations are found in the W3C Navigation Timing Draft ( https://dvcs.w3.org/hg/webperf/raw-file/tip/specs/NavigationTiming/Overview.html ). Network time is connectEnd minus navigationStart. Server time is responseEnd minus connectEnd. Finally, client time is loadEventEnd minus responseEnd.

User reviews

Great work, but please add an on/off toggle so it doesn't show up all the time

Wonderful extension, the only thing it does miss is the ability to configure which domains are to be benchmarked instead of all pages and the ability to compute average values for each (sub)domain.
