macbre commented 10 years ago

Hm, there are actually more issues when loading rackspace site using phantomas:

'[object Object]' is not a valid argument for 'instanceof' (evaluating 'node instanceof Node')
10:47:25.001 Backtrace: getDOMPath(): /core/scope.js @ 229

I see non zero value of timeToFirstByte metric, however it seems to be calculate for a JS asset instead of HTML response:

10:47:24.285 Time to first byte: set to 89 ms for <http://libs.coremetrics.com/eluminate.js> (HTTP 200)

I'll take a look. Thanks for bug report.

macbre commented 10 years ago

JS assets included at the top of the page were fetched before the HTML response finished to load causing race conditions.

Fixed by #299

awesome thank you
