Sftp Performance

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

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. 

The version of terminals:

All test data is for reference only.

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)

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:

Test command: "time seq 1 n" (n = [1000000, 2000000, 5000000, 10000000], scrollback lines: unlimited)

n = 1,000,000

n = 2,000,000

n = 5,000,000

n = 10,000,000

n = 10,000,000 scrollback = 30 Lines

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..

The version of terminals:

All test data is for reference only.

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)

In all cases, three runs were made to warm system caches. The reported numbers are the median of five runs.

Test command: "time seq 1 n" (n = [1000000, 2000000, 5000000, 10000000], scrollback lines: unlimited)

Latency

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