I have a BayTrail system as well. From my playing around with it, I have found that Endless is about the only Linux based system that does usable job of supporting the architecture. But it is still very slow with Endless.
I keep any responsiveness in my BayTrail it is really necessary to run only one major application at a time. For Chromium try and stick with only one tab open. You can install extensions from Chrome web store. I use uBlock Origin to block ads and stop tracking, which can help a fair bit. There are also extensions to block multi media from playing/loading automatically.
For multimedia Totem (Videos) and RhythmBox (Music) both use codecs and frameworks that are part of the Gnome system and most likely are less resource intensive than VLC. You can use Totem (Videos) to play Youtube videos as well.
The Youtube app, the Gmail app and perhaps others as well are web apps built on Chromium, so having any of those apps open essentially counts as having a Chromium tab open. You can turn off auto upates, turn off Bluetooth and where possible block push notifications, which will also conserve system resources.
Baytrail was a dead end for Intel and it has been discontinues for some time now. But there were a large number of inexpensive systems built upon it. It does have very good energy usage proprieties and thermal properties. It is nice that Endless supports the architecture, It is slow and easily stressed, but if you keep reasonable expectations of what can be on the machine, it is good serviceable hardware.
