=== Notes === | |||
* tpaint measures the time it takes to paint the content for a new window that has been '''opened from content'''. Windows can be opened from content in a few ways: | |||
** The content runs some JavaScript that calls window.open with non-default features, like window.open("https://www.mozilla.org", "_blank", "toolbars=no"); | |||
** The user has flipped the browser.link.open_newwindow pref from its default to open new windows instead of new tabs, and then clicks on a target="_blank" anchor | |||
* tpaint '''does not''' measure the time it takes to open a window triggered from the parent. Windows can be opened from the parent in a number of ways: | |||
** The user uses Ctrl-N or File > New Window to open a new window | |||
** The user clicks on a link in another application that opens the browser the first time | |||
** The user right clicks on a link in content, and chooses to Open Link in New Window | |||
** The user tears a tab out into a new window | |||
* An experiment was conducted to determine whether or not e10s regresses opening windows from the parent. | |||
** The experiment was conducted in {{bug|1251732}} | |||
** '''The conclusion was that e10s does not regress this case.''' | |||
* We suspect there is a second slow-path here that Talos is not measuring, and that's when the user clicks on a link that opens a new tab. | |||
** A bug has been filed to add such a test ({{bug|1253382}}) | |||
