I think this was posted to HN before, but in any case, related: http://isitsnappy.com/ http://isitsnappy.com/ It's an iOS video app for measuring latency. The page has this about Apple keyboards: "This one’s bizarre: the onboard keyboards on both the 2015 Macbook Pro and Macbook Air have worse latency than an external keyboard. Plugging in an external wireless keyboard improves response latency by 40 ms."

The MacBook Pro 2015 doesn't use an USB connection to connect the internal keyboard when using macOS. Instead it uses SPI. Unlike the newer MacBook Pros it still has the keyboard wired to USB, but doesn't use that because of power saving reasons.
