It is like 10GB download and it takes a decent amount of time to download and compile. They don't make it that easy.
Basically this is an optimized browser made for the snapdragon processor. I have been running it for a few weeks and it is pretty solid. Really fast. I did some benchmarks vs firefox and chrome and it is between 10% - 30% faster. It just seems snappier than other browsers.
Here are images of the benchmarks.
Here is a screenshot of the browser
The older version of SWE built by this guy:
Actually had better sunspider scores, but the newer version is much better at octane and kraken.
However it looks like since google switched to the blink engine sunspider is no longer something they are optimizing for. However the SWE browser scores are still 30% faster. It asks for a bunch of permissions. I am not sure which ones are actually necessary so I left it as is.

Update December 27th:
This is my version of the m46 version of the browser:
I have put an updated version of swe browser on the play store. I have been using this for the last 3 weeks. I modified it slightly from the qualcomm version since the qualcomm version tries to launch apps from google search.
This is the m42 version with the AD blocking.
This is probably the best browser out there in my opinion.
