THE VIDEO SHELF · terminal rendering performance
Refterm v2 - Resource usage, binary splat, glyph sizing, and more
Casey Muratori follows up his refterm proof-of-concept, a GPU-based terminal renderer, with a second part covering memory usage, glyph sizing and correct Unicode and VT handling. It is built to show that a terminal can be fast and correct without heroic effort.
Why HN readers recommended it
HN points to it as proof that a small, straightforward renderer can beat Windows Terminal on speed and memory, whenever software slowness comes up.

In his follow up video[0], he shows that in-use-memory is half that of Windows terminal, whilst simultaneously being >100x faster. Windows terminal chugging away in the background consuming 20% CPU for minutes at a time whilst he's debunking these claims / running the same data …

In Looking at the Performance of ReftermYou should look into Casey Muratori's quest[1] against Windows terminal slowness on github and youtube. There were some heated exchanges there and some proof of concept software created to demonstrate both how slow Windows Terminal is, and how fast a GPU enabled terminal can be. …

In Warp: Fast, Rust-based terminal (waiting list)For reference, I've never seen the built-in Windows VPN protocols exceed ~70 Mbps in any scenario. Maybe it's possible with a crossover cable between two Mellanox 100 Gbps NICs, using water-cooled and overclocked CPUs, but not over ordinary networks with ordinary servers. I have gigabit …
