Very nice!
I love both the underlying focus on performance by the VTE developers, and the intense hardware-driven measurement process in the article!
The use of a light sensor to measure latency reminded me of Ben Heck's clearly named "Xbox One Controller Monitor" [1] product [1] which combines direct reading of game console controller button states with a light sensor to help game developers keep their latency down. It looks awesome, but it's also $900.

- blueflow 3y agoThe focus on performance is a recent thing. VTE was pretty slow to begin with.
- amaranth 3y agoThe focus on _latency_ is a recent thing. VTE was previously focused on throughput and low CPU usage, which are conflicting goals.
- bobmcnamara 3y agoFun fact: if you have vsync enabled, latency depends on where you position the sensor.
