WindTerm is a partial open source project, and the source will be gradually opened.

Open source code includes, but is not limited to, the classes that can be used independently, such as functional, algorithms, gui widgets, etc., as well as functional libraries, such as network, protocols, etc., as well as all types that require open source according to the license.

Any issues and feature requests are welcome.

The hardware used for generating the data in these benchmarks was

windows 10 - 2.3 GHz Intel Core i5 and 8GB memory.

WindTerm1.72, WindTerm 1.2, FileZilla 3.48.1, WinSCP 5.17.2 (Build 10278) tests are performed on WSL(Ubuntu 18.04.2).

The version of clients:

All test data is for reference only.

• 5GB huge file (5,154,830 KB), generated by random data

• 4400 files, 16 folders (107,042 KB), unzipped from vim-7.4.1049.zip

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. 

The version of terminals:

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.

1. Telnet:

2. SSH:

3. Shell:

• time seq 1 n

1. n = 1,000,000, scrollback = 1,000,000 Lines

2. n = 2,000,000, scrollback = 2,000,000 Lines

3. n = 5,000,000 scrollback = 5,000,000 Lines

4. n = 10,000,000 scrollback = 10,000,000 Lines

5. n = 10,000,000 scrollback = 30 Lines

Considering the network influence on the latency, the following data is from WindEdit. DIGEdit is the text component of WindTerm.

Release cycle:

2-4 weeks.
