This is quite dramatic, in that I can actually feel my Macbook not heating up as much, nor can I hear the fans anymore.

We do quite a lot of work on a trading website that has heavy use of Canvas and CSS animations, and the latter really kills performance. Two runs on our production website from Intel Power Gadget, pre and post upgrade, show decreased temperature, a lot fewer power spikes, less DRAM wattage, lower GFX clocks, and about 40% less power overall:

Bitmex looks very interesting, any fun stories to share?

Given the extensive market manipulation and liquidation of margin traders in cryptocurrency, probably nothing that can be shared publicly.
