      The refterm lecture series is now complete. If you'd like to watch the entire breakdown of how I got ~1000x the throughput of Windows Terminal without really doing any optimization, here is the playlist:https://www.youtube.com/playlist?list=PLEMXAbCVnmY6zCgpCFlgggRkrp0tpWfrn …

      [And some notes: as mentioned in the lecture, refterm only had ~100x the throughput prior to the one part that was optimized, which was the ingress parser. With a ~20 lines of optimization, the throughput went up another 10x. The rest of the code is still mostly unoptimized.]

      [Finally, it's worth noting that this throughput is still potentially very slow compared to what would happen if I had gone all the way and made "fast pipes" that communicate through L2-sized shared memory directly. So 1000x throughput is, in many ways, not even "good".]

          Any response from @Microsoft on this? I know this started as a dialogue with them; have they responded since you’ve proven that you were right? Will you try to communicate with them through the same system again?

          Well... They did open an issue and said they'd implement something like Casey did. I, personally, find the whole issue hilarious.https://github.com/microsoft/terminal/issues/10461 …

          I think it is safe to call it good, not because it is as fast as it can be, but because it seems to be a reasonable compromise between speed, readability/ease of maintenance and time spent. Optimization is always a tradeoff, speed can even be a secondary goal.

          I’m curious about this “fast pipes” technique. Have you spoken about this on stream before?
