Refterm Lecture Part 3 - Minimal Buffer Processing

Over just the past few months there was all this hubbub about building a high performance terminal emulator for Windows since Microsoft is unable to do so. Here's that series: * How fast should an unoptimized terminal run? * Refterm v2 - Resource usage, binary splat, glyph sizing, and more * Refterm Lecture Part 1 - Philosophies of Optimization * Refterm Lecture Part 2 - Slow Code Isolation * Refterm Lecture Part 3 - Minimal Buffer Processing * Refterm Lecture Part 4 - Glyph Hash Table * Refterm Lecture Part 5 - Parsing with SIMD Source: https://github.com/cmuratori/refterm

…bitmap stuff was wasteful. How do you think TTF rendering works? It's the same thing! The only difference is that you use a font renderer to build the raster font at startup from a vector font. Check out this short series about refterm, which deliberately uses a slow system font renderer, but places a hash table in front to amortize its costs: * link to this video * link to this video * link to this video * link to this video * link to this video * link to this video * https://github.com/cmuratori/refterm…
