Author here, I will try to implement your suggestions. I made the benchmarks out of curiosity and excitement for ghostty release and never intended to pick on any specific terminal. Considering it's first initial release (1.0) ghostty performance is very good and I'm sure it will improve even more given a few months. I know ghostty doesn't just focus on performance, it excels in other area like utilizing native components and having a growing community that is very supportive.
