Simple Performance Bar Extension

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.

Jan Romme (ID: 000000c9910f1857) Voted 4 ★ - Updated 09/30/2020 Great work, but please add an on/off toggle so it doesn't show up all the time

icon

Sorin Sbarnea (ID: 0000007e4fbdce89) Voted 5 ★ - Updated 06/15/2015 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.

Laur Rent (ID: 000000788b40b87a) Voted 4 ★ - Updated 01/20/2015 This is really nice. Well done. It would be better if it as possible to easily toggle it (on/off) as it gets annoying when you have it on all pages.
