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.

- (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) Josh Hartman: This works great. Very slim UI that is easily able to break down performance by network, rendering, and server-side latency

Great extension. Two suggestions: First, I agree with Laurent. The ability to turn this on/off with a button would be great. It wouldn't interfere with the simplicity. Second, if there were 2 or 3 bar heights to choose from, it would help people working on laptops. Great app.

Would be perfect if it was possible to easily toggle on/off as having this bar all the time is a little annoying. Very nicely done tool. Congrats.
