Description Vance Dubberly 2008-06-04 14:03:31 PDT
When using the network timeline in web inspector to check load times I notices that requests that show up in Firefoxes time line as taking 3-5ms show up in Webkits inspector as taking 180-225ms. I double check this against ab  and Firefox is accurate.  I've checked this against a number of sites... for instance yahoo( 69ms vs 282ms )  and google (10ms vs 367 ms).

Maybe we're not measuring the same thing?

What's "ab"?
Comment 2 Vance Dubberly 2008-06-05 21:06:46 PDT
While ya'll make in fact be measuring the metric differently, the timeline appears to mean "it took (n) milliseconds to load (x) resource".  I think most people will believe that means "request initiated thru server finishes transmit." Which is what  mozilla ab, httperf etc measure.  ab = Apache Benchmark...  <APACHE_ROOT>/bin/ab

Has this changed now that we show latency separately?

The times reported in the bug congrue with currently-rendered "download" vs "total" times, closing.
