1096321 - Treeherder is painstakingly difficult to use with e10s enabled

Status: RESOLVED WORKSFORME

(Core :: DOM: Content Processes, defect)

Description

[Ryan VanderMeulen [:RyanVM]]

On my company-issued W530 laptop w/ 24GB of RAM, quad core CPU w/ hyperthreading, etc, I see very long lag times switching between Treeherder tabs. I'll get an empty content area for multi-second delays, which adds up to a big productivity hit when trying to actively sheriff the trees.

It's less of an issue when I increase the number of content processes to match or exceed the number of treeherder tabs opened. Each TH tab then ends up in its own process, so everything isn't lagged out by some tabs fetching and displaying new job data.

Treeherder performance hasn't been problematic w/ e10s enabled for quite some time.
