Original Pull Request: https://github.com/microsoft/terminal/pull/15499

State: closed
Merged: Yes

Performance of printing enwik8.txt at the following block sizes:
4KiB (printf): 78MB/s -> 93MB/s
128KiB (cat): 117MB/s -> 156MB/s

The change itself is rather self-explanatory.
A tighter, simpler loop runs faster.

Validation Steps Performed

Mixed ASCII/Unicode text output looks generally correct. ✅
