Original Pull Request: https://github.com/microsoft/terminal/pull/18287

State: closed
Merged: Yes

This increases the console IO buffer size to retain at least 128KiB as this matches the default buffer size of cat. This avoids allocator churn due to constantly freeing and reallocating buffers. In the future this should ideally use a better suited, cheap allocator.

Closes #18286
