Not sure you can do anything there, unless you intend to change the chromium source. The problems here are on the hardware level, which you're, owing to sitting on top of chromium, far removed from. That said, i don't use Postman, heard of it the first time today. But you might be able to reproduce some of the issues by loading a very animation-heavy imgur page like https://imgur.com/a/0L8Bu https://imgur.com/a/0L8Bu , scrolling to the gifs, maybe zooming out a little to get more on screen, and starting up a bunch of different electron apps. Particularly helpful would be using https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspx https://technet.microsoft.com/en-us/sysinternals/processexpl... to keep an eye on the interrupt CPU usage. Once you start seeing lots of red activity you're getting close.
