# Terminal Performance
The hardware used for generating the data in these benchmarks was
windows 10 - 2.3 GHz Intel Core i5 and 8GB memory.
MacOs 10.13 - 2.3 GHz Intel Core i5 and 8GB memory.
**WindTerm 1.72, rxvt, putty, xterm, Windows Terminal** tests are performed on WSL(Ubuntu 18.04.2).
**Iterm2, kitty, Alacritty** tests are performed on MacOS shell,
For WindTerm: No color scheme used in windterm. Color scheme will result in approximately 2% loss and more memory usage.
For Alacritty: Only supports up to 100,000 scrollback lines, so every test use "history: 100000" setting and no memory usage measured.
For Windows Terminal: Only supports up to 65,535 scrollback lines, so every test use "historySize: 65535" setting and no memory usage measured.

## Test Command: "cat ./benchmark_randomdata"
The benchmark_randomdata contains 97.6MB random text (102,401,504 bytes, 1,329,878 lines, generated and tested by [random_test.sh](https://github.com/kingToolbox/WindTerm/blob/master/benchmark/urandom_test.sh))

# Linux Terminal Performance
The hardware used for generating the data in these benchmarks was
Debian 10 Vm - 4cpu and 4GB memory.
For WindTerm: No color scheme used in windterm. Color scheme will result in approximately 2% loss and more memory usage.
For other terminals: No memory usage measured because most of them write the history to disk or only support a limited number of lines in memory..
