I frequently compile big software projects, using fast multi-core CPUs, like AMD 9950X, with which the compilation itself is really fast.
Such compilations produce a ton of text messages. With any classic terminal, the text rendering in the terminal window becomes a bottleneck, slowing down the compilation very noticeably.
With modern terminals that use GPU text rendering, like ghostty and kitty, compilations are done much faster.
To see the difference between a slow terminal emulator, like you probably use, and a fast terminal emulator, you can do a "cat" from a text file of a few megabytes, and you will see the speed difference.
