Simple site performance bar that presents network, server, client and pageload times
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.

- (2020-09-30) Jan Romme: Great work, but please add an on/off toggle so it doesn't show up all the time
- (2015-06-15) Sorin Sbarnea: 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.
- (2015-01-20) Laur Rent: 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.
- (2015-01-08) Ritesh Maheshwari: Thanks Oliver! Awesome work!
- (2015-01-08) Josh Hartman: This works great. Very slim UI that is easily able to break down performance by network, rendering, and server-side latency
