Subject: RCFilters: Log performance data
X-Git-Tag: 1.31.0-rc.0~1955^2
X-Git-Url: http://git.cyclocoop.org/wiki/Target_page?a=commitdiff_plain;h=b3f9593262f1f5fa1909941bbc68d89bae2b0495;p=lhc%2Fweb%2Fwiklou.git

RCFilters: Log performance data

Just UI ready time and wgBackendResponseTime for now.
Sanitizing responseStart and especially firstPaint cross-browser
is too messy. NavigationTiming has code for it but that would
need to be exposed somewhere.

Bug: T176652
