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, rxvt, putty, xterm 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: Can not find how to set the scrollback lines limit, so every test use its default setting and no memory usage measured.
The version of terminals:
windterm v0.8
rxvt-unicode: v9.2.2
putty: v0.71
xterm: v3.30
iterm2: v3.3.6
alacritty: v0.3.3
kitty: v0.14.6
All test data is for reference only.
- 97.6MB random text (102,401,504 bytes, 1,329,878 lines, generated and tested by random_test.sh)
In all cases, three runs were made to warm system caches. The reported numbers are the median of five runs.
